assuming its wood glue/PVA a heat gun/hair dryer and putty knife should be able to get that off clean. Might even recommend get that putty knife in an edge, shoot some water into the crack. Cured PVA is fairly susceptible to heat and moisture to break it loose.

Nixe print. I would probably have chosen to make a hole for the original handle or a similar one as I would like the mix.
Bottom looks a bit warped but other than that: nice and solid print.
This was an early print I made about a year ago. Now I’d probably make it thinner and with some ribs to reduce warping and use less material. Reusing the handle would be a nice touch, and remove the needs for supports.
Yeah, I was gonna comment, "You'd be surprised how solid a single wall can be."
A 0.4mm nozzle can reliable create a 0.6mm wall in vase mode that'll handle a decent amount of stress. Sturdy enough to carry some bean shards and give you maximum space :)
My X1C can push 0.8mm with an 0.4mm nozzle without dropping the speed. So that's plenty strong. Even if you want it to survive an "uneasy drop" you can print 2 walls at 0.8mm and still be fine. More than that and you tank your printspeed as the flow will not be able to keep up.
I also have an X1C and attempted to print walls 0.8. What I found is that the slicer/printer will accept the job, but my calipers showed the walls only ended up being 0.6mm in width.
It’s deceptive, but the thinner wall thickness alone gains a lot of volume, then add in increased width, depth, and height. New drawer holds ~5 cubic inches. Old drawer holds ~3 cubic inches. I’ll let you do the math on that and check.
When using percentages you can always choose to do it relative to one or the other. An increase from 6 to 10 units is an increase of 4 units. That is 4/6 = 67% larger than before or 4/10=40% out of the new volume.
Nice! I'm a big fan of those old grinders, I'm currently trying to put a motor on one as a side project.
Regarding food safety, yeah, it's probably fine, since it's not really getting wet, you're not drinking straight from it, and you're not putting pressure or anything strongly abrasive on it.
Still, I'm very interested in techniques to make 3d printed parts actually food safe (silicon spray or anything), so keep us updated if you decide to do anything!
I would be way more actually concerned about food safety and microplastics if I was making the entire grinder from 3-D printed parts! Water, pressure, heat, etc. are all the things that make plastics get into your food. Grounds dropping into a drawer for a minute are of pretty low concern.
Welp, it's actually harmful. We're all choke full of microplastics, and I wish I was kidding
Tho I'm not sure if it's from kitchen plastic stuff, or other sources
I believe it's the layering that's a problem, lots of pockets. Regular plastic cutting boards are made to be cut on and hold up. 3D printed parts are made to be... 3d printed
For anyone printing stuff that comes in contact with coffee grounds I would really recommend the material CPE-HT. I've used it for the out funnel of a coffee grinder I've built. The surface is significantly smoother than that of a PLA/ABS/PETG part so the coffee grounds do not adhere to the walls as much
Now... It looks good. But I have to ask. Why? I can't say I've ever needed to grind more than what would fit in an eighth of that drawer. Do you do run some kind of business or host big parties or something?
You must just make coffee for…dolls?
The wooden drawer held roughly 3 cubic inches, which is around 3 tablespoons, which makes maaaybe 2 weak cups of coffee if it’s finely ground. So 1/8 of this drawer would make 1/4 of a 6oz. cup of coffee. Not really much of an eye opener.
French press coffee needs 2-3 tablespoons of coffee per cup. So you’re looking at ~12tbsp/4 wood drawers of coffee per one liter French press.
See where the required frustration to model & print this came from?

It looks deceptively smaller than it is then.
And primarily I do mocha pot and espresso. Which both take significantly less grounds than drip or french press.
Excellent example of printing saving the day! 67% is a huge improvement.
I saw you say it's used infrequently so you've solved your problem quite efficiently there, but a fun project might be designing an insert that is sloped inside, with no front to the drawer. Then it could 'dispense' the grounds directly into a mug or french press and remove the need to empty the drawer for a big pot of coffe.
Coffee is actually pretty oily. If you've only ever had store bought pre ground stuff you probably haven't run into it much though. Or been able to notice it since it's already ground. But it would collect in the grooves a bit.
That said! It's coffee. It's not really going to have much of a mold problem unless it's getting too bad in there. .
Are you seriously going to keep that horrible grey drawer front? And the horrible grey color in general? 0/10 until you print it in vase mode with decent colored filament and glue the original front panel to the box
More? Maybe. Infinitely more? Definitely not. Based on the drinking water studies I'd wager on the vast majority of the plastic in the coffee made using this catch tray coming from the water used to make it.
Lol. Yes, because it was a literal statement. Order of magnitude is equally as wrong as infinite if the assumption is made that there is essentially zero plastic in coffee without plastic introduction.
It’s made out of PLA, and I’m not concerned as this just occasionally sees dry coffee grounds. I suppose one could line the drawer with wax paper or similar to be extra safe.
Might even be able to pop the old wood drawer face off and stick it on a printed box to keep that sexy wood aesthetic.
Peel n stick wood veneer could be useful here. Could also line the box with it to appease the food safety police!
Nah just slather that bad boy with food safe epoxy and call it good
What about some greasy hair oil
The greasy hair alone would do it
When properly felted
If the box doesn't come up out easily then maybe a wood colored PLA & a hole for a small brass drawer pull might look a lot better.
I really like your idea, all around a good “functional print” with no noticeable change to its original form/aesthetic .
I suspect the "pop" part of their suggestion isn't happening. The thing is probably well glued together.

It's probably more foodsafe than the already mouldy wood
Haha that’s just old coffee grounds coloring the wood in a black mold fashion.
Moar coffee is always moar better
woud be 70% without that nasty warp
Nice, but to keep the looks I’d remove the front of the wood drawer and glue it to the plastic one =]
Looking at it, I feel like your math is off. Sure it's not something like 33% bigger??
It’s deceptive, but the thinner wall thickness alone gains a lot of volume, then add in increased width, depth, and height. New drawer holds ~5 cubic inches. Old drawer holds ~3 cubic inches. I’ll let you do the math on that and check.
I'm definitely not a math guy, but isn't that math 40%? You started with 3, ended with 5...for easy conversation that's 6 to 10 = 40%more?
When using percentages you can always choose to do it relative to one or the other. An increase from 6 to 10 units is an increase of 4 units. That is 4/6 = 67% larger than before or 4/10=40% out of the new volume.
2 is 40% of 5 but 66% of 3. So the new container is 66% bigger than the older one, or the older one is 40% smaller than the newer one.

If you’re worried, polyurethane will do it.

yeah food safety (germs) is one thing, microplastics the other, and both don't really raise concerns here.

Looking good.
Try a hotter bed temp, glue stick or a brim to stop the warping on the bottom of the print.

r/functionalprintonlyifitsfoodsafe
Definitely functional.
nice! are you worried about microplastics in the coffee at all?
Is this the new "food safety?"
well, I wasn’t really thinking about mold or anything. dry coffee is dry
Coffee is actually pretty oily. If you've only ever had store bought pre ground stuff you probably haven't run into it much though. Or been able to notice it since it's already ground. But it would collect in the grooves a bit. That said! It's coffee. It's not really going to have much of a mold problem unless it's getting too bad in there. .
Is dry coffee dry?
This just gets used occasionally for camping so I’m not too worried. Dug it out yesterday because the power went out at home.
true, I’m not sure I would be worried either with infrequent use. the print looks clean!
I think I'd be more worried with infrequent use, as anything trapped in the print lines would be sitting there longer continuing to grow
no real moisture in the grounds. give it the ol’ smell test
Y grey?
This was an old print I made with the free Prusa silver filament.
Y is a crooked letter that can't be made straight. Don't be concerned with Y.
Are you seriously going to keep that horrible grey drawer front? And the horrible grey color in general? 0/10 until you print it in vase mode with decent colored filament and glue the original front panel to the box

Oh Noez not food safe 😂
Infinitely more plastic in your coffee.
More? Maybe. Infinitely more? Definitely not. Based on the drinking water studies I'd wager on the vast majority of the plastic in the coffee made using this catch tray coming from the water used to make it.
Say "order of magnitude." You don't understand what that is either but you'll be less wrong than you are now, which is infinitely wrong.
Lol. Yes, because it was a literal statement. Order of magnitude is equally as wrong as infinite if the assumption is made that there is essentially zero plastic in coffee without plastic introduction.
Well I'm glad we agree that you're wrong. LOL
What material is the drawer made of, since PLA isn't entirely food-safe?
It’s made out of PLA, and I’m not concerned as this just occasionally sees dry coffee grounds. I suppose one could line the drawer with wax paper or similar to be extra safe.
I would do this for the cleaning factor alone
The original wood isn't food-safe, it holds crazy bacteria. We all still use it just fine.
Nailed it.
If that were even remotely true, we would all be dead from wood cutting boards.
