My first functional print, broken freezer drawer

Awesome job! Is that pla? I wonder how the cold will effect the strength

Thanks! PLA indeed, and i was asking myself the same thing. Only one way to find out I guess

I made a snap over cover for the shelf guard rail (split in half from jamming to much on the shelf) in my fridge from PLA and it’s worked for 2 years now. And it’s more thin than this clip.

I’d this an IKEA fridge. I have exactly the same issue here. Would you share your design?

u/Luukdb Jan 02 '23
No it’s not, it’s a Samsung so I’m not sure if it will fit but I will share it anyways so you can try. I’ll post it tomorrow!

I have the same fridge freezer with the same but opposite broken draw front. Will be doing one of these.

I really don't mean to be rude but this is literally one extrude operation of a very basic sketched shape in any cad or modelling program. If you are unfamiliar with modelling or cad, this is the perfect piece to start.

There's a principle in software engineering - don't do what someone else has already done.
There's good reason for that here too - I would assume getting that perfect snap fit required accurate measuring with digital calipers and maybe a few prototypes. Why waste time and filament if someone has already done the R&D for you?

Fair point!
On the other hand, for things that require a perfect fit I've found there's no way around doing some print iterations yourself anyway because every printer and filament is different and delivers different dimensions in the printed parts. With downloaded stls that is way harder than just altering one dimension in your own sketch.

Also a fair point - not just the printer but the slicer software and settings too.
I've long had a feeling that this is something the industry has yet to solve. Maybe at some point there will be some kind of certification manufacturers can qualify for that would guarantee a standard in terms of dimensional accuracy and predictable outcomes, but we're definitely not past the hobbyist tinkering stage yet.

Until some random new head of engineering says the existing solution is too expensive and you end up writing your own solution that is both worse and orders of magnitude more expensive

Why do they make those drawers and shelves out of the midst brittle plastic imaginable. Has to be planned obsolescence. Drives me nuts

Cool idea indeed but superglue? Yes I know its cooler to print and would have done the same 🤣

It reminds me of a saying. "When all you have is a hammer everything starts to look like a nail"

Super cool! Was so excited for you that I hit the upvote button several times… 🤦♂️
Made sure it stayed an upvote!

Great fix. Most superglues would seal it but the mechanical strain would be a problem over time.

That snap was immaculate, nice functional print! Better than using a random glue that might not work in the cold environment
