Hope you seal that bad boy up or it's going to be a nice home for all those microorganisms.

Yeah didn't tought of that, do you think epoxy resin is enough?

[–] PurpleClouds@lemmy.world 2 points 2 days ago

Food safe epoxy would be fine I think. Don't get the cheap stuff.

Salt annealing!!! I just saw a video on this: link

Hey, could you show us a bit more perhaps? It's not very clear what you fixed exactly.

[–] moody@lemmings.world 9 points 3 days ago

I think they meant a piece of glass. Looks like what would go on top of the cheese drawer in the fridge.

Had to make a second version because the one on the post was too fragile. It was bending with just the glass. The new one looks like this

[–] technomad@slrpnk.net 2 points 2 days ago (1 children)

Oh, nice fit! Are you pretty satisfied with it so far? I don't imagine it would have any issues with the cold temps, and it pretty much looks like it came with the fridge. Good work!

Yes, it looks better than I expected. I will seal it later to prevent bacterial growth as someone suggested here

Was confused by the title. "How do you have a cup too small for a fridge?"

Id love to know how you got the first layer to stick, I couldn't get my Cr-30 to print anything more then spaghetti.

At the beginning I had several issues. If I remember correctly first I has to level the front part, then mark the distance with a wedge and have that same distance on the back.

For this it is important that when you're adjusting the Y0 check on both edges and in the middle. It should be the same height overall

Once it's leveled you need to adjust the Y offset until it sticks, for this you can print a zigzag pattern and it should stick equally well everywhere.

I remember I had saved some videos that explain that let me find them. Also the discord community is helpful for this particular printer

This is the kind of shit that always sells 3d printing to me, when is see someone solve a whacky problem they have that otherwise would be kinda hard to pull off.

I’m guessing that these days the filaments/resins are getting pretty high durability on the consumer market?

The durability comes with the design and the material used. As I said on another comment the first version was very fragile and was bending with barely any weight on it.

After adding a bracket to hold the glass in between it keeps its form even with food on top. It all depends on how you design the piece and in which direction you print. Not always the easiest way to print is the best for durability.

3D printing is not as strong as injection molding the same material in the same shape.

But you can beef it up. You can 3D print stuff much bulkier than injection molding can do.

If you really want to, you can also use stronger materials.

Also, even the weakest cheapo stuff you can get is plenty strong for most stuff people are printing.

Knowing about what makes a part strong or weak helps a lot.

[–] Hotspur@lemmy.ml 3 points 3 days ago (1 children)

Yeah ok makes sense. Plus like you said you can always over build the piece, etc. and if it breaks after a few months, you can always reprint it haha.

Also, one of the biggest killers of 3D printed parts is heat, and the other is ultraviolet exposure. If OP is putting this in his fridge I think it's in the one place it's going to encounter very little of both.
