Sub Zero Refrigerator Drawer Guides

This project involved making new slider brackets for the lower drawers in the refrigerator portion of the Sub Zero refrigerator - one of which was completely broken and one that had plastic bearings that were totally worn out and flat-spotted. 

With about 4-5 hours in Fusion 360, I was able to produce an almost exact copy of one of the brackets (the unbroken left side), and I was able to make it even better by making the walls thicker, the screw hole walls thicker and used real metal bearings instead of the cheesy plastic bearings that were originally installed.

Because the brackets were much longer than the print bed of my X1 Carbon could print, I imported the .stl, then cut the bracket into two pieces, mirrored both pieces (for the right side) and stood them vertically to print. I made a rectangular piece to fill in the channel in the rear of each part and used a negative part cylinder to cut out the relief for one of the screw holes, which then allowed me to super-glue the two bracket pieces together. Once the glue dried, they are MASSIVELY stronger than the original pieces.

I sourced some 6x19x6mm metal bearings from Amazon (10 for $7). I printed small (2mm) sleeves/spacers for the new bearings and replaced all the cheesy plastic bearings that were original equipment, and now each drawer glides like butter.
