Refrigerator Door Bin: Replacement for Samsung DA63-08646A

This replaces Samsung part DA63-08646A used in the RT21M621 series of 21.1 cubic foot refrigerators. I've had two of these brittle door bins break in less than 3 years. (The rest of the refrigerator is great.) Each OEM replacement costs $90+, takes 3+ days to ship, and will probably need replacement again in a few years, so I decided to 3D print my own. 3D printing is definitely cheaper and faster for me. I simplified the shape a little to make it easier to model and print. I also added a pattern on the front to make it rigid.

I printed the part in PLA on a 350x350 Voron bed, but it should be fairly easy to cut up the model into different sizes for smaller printers. I used “lightning” infill to minimize the amount of filament required; I think the total was about 0.8 kg. I split the part into 3 pieces that I stitched together by sliding raw PETG filament into the channels. I generated and used models for the support material so that PrusaSlicer would generate the exact supports I needed and no more.

The final piece is surprisingly strong and rigid and I don't think I used any adhesive. I did have to cut off the mouse ears, file the prints, and drill out the holes so the filament could slide in. The new bin has been in service for months with no issues.

I included pictures of both the original bin and the 3D printed bin. This is the first completed draft; it could use some refinements (it should be a little wider and the tabs should be a little thinner to fit better), but it works well as-is. I think PLA is more durable than the original material.

I really enjoyed the weaving technique I used. It seems like a great way to print and connect models too big for the printer. It ensures the final part is strong and has the exact dimensions specified in the model. I haven't seen any other prints connect this way and I hope other designers try this technique for their models.

The OpenSCAD source file is included. It depends on the open source BOSL library.
