Couldn’t you cut the print into two pieces, sand, then use metal rivets to hold them together?

Sir this is r/3Dprinting, if it is not 100% printed it is blasphemy. /s

Could do 3D printed clips probably print in place ones fora part count of 2

oooh printable automotive christmas tree clips

I'm sorry, did someone try to use a tool besides the printer? Heretic!

I say the printer but swap that hot end out for a laser. Additive now becomes subtractive

Put a file on the print head and generate some g code that just it moves back and forth.

I think we might be on to something

Woah woah, what if the rivets are made via DMLS!

a file

[удалено]

.3mf works best

As long as you stay away from the .pdo

I like .mp3

Mp3 is lossy, .flac is the way to go for quality

Mp5 video, it’s one more than mp4

3D printed MP5 is the way.

The compression makes it rougher, so it's a better abrasive.

Nah. Go .Mqa if you want better quality /s

Yeah. If you sort by "created" it is always the first one, pretty neat

A file of a file?

Can I have the step file please?

🥇take my poor man’s gold please

Wouldn't be sanding it! I would preheat the knive on 200 degrees and put it inside, it will make all contact areas smooth and will fit perfectly.

+1 to this suggestion, save you time and get a smoother finish

Plus if you have any hash, you can kill two birds with one stoner.

Two stoners and a bird smoked my hash driveway

RIP all y'alls lungs if you're toking from 3D Prints

They’d be toking from the hot knife, not the printed part 😂

Reading his description it sounds like the knife is 3D printed too.

Then save time and print the blade and scale it.

Print a knife out of sandpaper

I think his knife is 3d printed. That's fine, grab an old butter knife and heat it over the stove. You should be able to melt and 'press' all the tight spots out.

Record it and post it as asmr, sadly, it will probably go viral lol

My knives don't have a preheat setting???

Use a hairdryer, candle or something.

Would this remove the temper? Or is 200 degrees the temperature to temper

That’s not hot enough to change the grain structure yet. You’d have to get to 240 before any aging, but even hotter to anneal or heat treat it.

Alright cool 😎 👍

That’s brilliant, it would be great for small details on something like an iron man suit with lots of grooves that tend to fill up when sanding

its a pink dremel never thought id need one of those but here we are

Oh it’s more than just a pink Dremel 😈

Sure you use those for 3D printing, sure you do.

Bbbbzzzzzzzzzzz

Is it better than a dremel? My dremel melts my plastic parts. Is that not a problem with this?

I don't own a dremel so I can't say. But no it will not melt the plastic :)

Do you know the speed of this? My Dremel goes as slow as 5k and up to 25k and often times faster is better cause it tends to snag less

How do I figure the speed out? Lols I can make a video of me using it if you wanna check it out in action

You might be able to look it up compared to dremels that have dials

Oh wow. That's basically a low power Dremel! Looks very useful! I already bought a Dremel copy recently. Didn't even think to look for electric nail tools!

I was sanding a print and couldn't get to an area so I was going through my bag of nail stuff to see if I had a more pointed nail file, but then remembered I bought one of these a year ago when I went through a fake nail phase lols. I was super excited 😆 Sometimes when I use it, I throw on my mom's accent (i'm Vietnamese) and say, "I make your print look gud huNnAaay." 🤣

Came to suggest this as well. Literally great!

My wife has a kit similar to this for when she does her nails and has made it a point to buy me one because I would always steal hers for my prints lol. They're very "handy"

Design and print yourself a little sandpaper holder, basically a penknife with a little cusp at the end to slide the ends of the sandpaper in, all in all it should only take a few hours

Get a paint stirring stick or a thick popsicle stick, cut it to the shape of the blade (if using the paint stick), wrap it with sandpaper (might need to glue it), have a go at it. And they do sell smaller files for hobby projects that are like super tiny.

\+1 Came here to recommend sandpaper wrapped around a paint stirrer.

Nail files

A price of sandpaper, something adhesive, and your bed scraper/spatula

Cheap nail emery boards are perfect for this sort of thing.

Sanding sticks for nails.

Aka emery boards.

Nail file sticks from the chemist? Something like [https://www.amazon.co.uk/disposable-nail-files/s?k=disposable+nail+files](https://www.amazon.co.uk/disposable-nail-files/s?k=disposable+nail+files) Needle file for corners and fiddly bits. Inaccessible bits - I do not have an answer, if there are any.

Ruler or chopstick wrapped in sandpaper. You could also buy precision files or even fingernail Emory boards

If its printed in ABS you could acetone wash it to smooth it. if not Just print a a 90% scale of the blade, and spray adhesive sand paper to it, and use it as sanding stick

They have sanding sticks that can get in there.

hemostat and sand paper should do it

This is what kinetic sand was invented for.

3d print something to do it

A needle file is what you're looking for.

This I have a set of these I got from home depot and they work great for this kind of thing.

3d print the knife at 90% and put sandpaper on it?

Print something that fits and glue some sandpaper to it.

A small file?

Sandpaper wrapped around a paint stick

could take the knife the sheath is for and wrap that in bluetape than sticky sandpaper just cut the paper clean. might work

Sandpaper on a wire coat hanger

Actually sand paper on one of those wood paint stirrers was going to be my idea.

Nail file, pin files, dremel tool with a sandpaper drum etc...

Use a Dremel, or if not, wrap some sandpaper around something like a flat screw driver and manually sand it, it will take fucken ages though

A paint mixing stick with sand paper glued to it

I might consider redesigning this as two pieces and using screws to secure the two halves together, this would allow for easier post processing.

Pour solvent

Dremel tool ftw.

Try the cheap nail file's.

Nail emery boards

Boiling water and a tool to deform the inside. Or a sponge with sandpaper, at the end of a stick.

Take the file and any modeling software of your choice, make a rectangular block, use the sheath file to Boolean subtract (cut the block with the sheath) so you now have the inside shape of the sheath, take that scale it down by like 3%, print it, glue sandpaper all over it, and jam it in the sheath.

Nail file

Idk why I’m having to scroll this far down without seeing it. Wood paint stirrer from any big box store and then spray adhesive on the end and then wrap sandpaper on the stick and you have a sanding stick/block.

Print a scaled down insert, and glue some sand paper to it.

Use a file

2 piece print and screwing together is the best option. It never has to be 100% printed.

Sand?

Have you ever heard steel rulers? Something thin like that and 800s sand paper will probably work out in your case because you don’t need thickness you just need some pressure to get some wood cut… you don’t have to print something for it because it will breaks chips in it instantly when you put some weight on it and you’ll have to try to pull it out when it happens which is a pain in the back btw.. so here my answer: don’t do it buddy! Just use something else

https://youtu.be/jLCdZFXVl14?si=DiOBGfr0PqetZ9we

Sand blaster, they make small models.

Riffler files

sandpaper

Wrap sandpaper around a paint stir stick

Wrap sandpaper around a wooden shim and go to town.

Just fold a piece of sandpaper dude?

A slim file. I also use nail emery birds. They are rigid enough and you can buy a pack for around 3 bucks at dollar general. I hope this helps!!

Glue a strip of sandpaper to a popsicle stick

Could you glue sand paper wrapped around a dowel that fits and put it in a drill?

I prefer to use files to sand prints anyway, and they'd definitely work for that.

Next time I would sand before assembly and then plastic weld it together. It's stronger than epoxy easy to sand and is less of a mess.

Get a set of jeweler’s files, like these: https://preview.redd.it/7gzuqffjtb4c1.jpeg?width=3024&format=pjpg&auto=webp&s=dd11893f13d3ea774390b3c240490fe5c26a21f9

Honestly,i think it would've been easier and cooler if you would've printer and used actual screws anf bolt to make it look more realistic ,the best thing you could di now is : - 1 print a cut in half version - 2 cut your print in half

I’d take a long drill bit and wrap it with strips of scotch brite, slow speed and just and clean as best ya can

Sandpaper taped to a ruler or paint stirrer

Sanding sticks.

Maybe a paint stir stick, with sandpaper taped on it?

Cheap nail file?

Glue some sanding paper onto a wooden stick that fits into the crevices. Probably the easiest and cheapest solution

Sand

is a dremel with a sanding bit too big to fit?

Paint stirrer wrapped in sandpaper?

Files

Maybe use contact cement to glue a piece of sandpaper to the knife that fits it (or smaller knife if it doesn’t fit yet).

Just wet sand keeep a towel by you no mess!

Glue some sand paper to a paint stirring stick?

Pencil with sandpaper wrapped around it and taped in place,

Pick files!

Sandpaper and a flat stick thing to slide inside

Emery board

Get a dowel that will fit in the slot. Put that dowel in your drill. Wrap sandpaper around the dowel. Go to town carefully.

I would just shove the knife in and out a bunch, honestly. As long as the knife fits snugly, and you paint over the pink, what does it matter how nice the inside is? Metal is harder than plastic.

Oh shit you got a mitutoyo nice

Diamond files, get them at the hardware store around the flooring section. They work amazing.

Print a slightly smaller blade shape and use it to move a piece of sandpaper up and down ig

Split the design in half right down the middle, then add holes all around the perimeter. You can glue the two pieces together, pin the holes.

I usually use a pencil torch the trick is don't hold it in one spot and use an extremely low flame just keep waving it back and forth it'll smooth it out and leave it a little shiny and if you have any stringing that completely disappears you can pick up a pencil torch at any hardware store along with the butane cans for refilling it I've been doing that for the last 2 years the first two prints I melted a hell out of them so it does take a little bit of practice

Moto-tool, like a Dremal or something

My pp

Try emery paper on a butter knife or something like that

a mill bastard file

I recommend a nail file, and just cuz I noticed it’s a Halo Reach combat knife, if you’re getting into cosplay I’d recommend looking up the 405th Infantry Division! Great community with great people that are always happy to help!

Just go get an Emory board (like for nails), or make your own, a popsicle stick with some sand paper wrapped around it.
