Metal Storage Shelving Unit Feet

thingiverse

I got a budget-friendly storage rack ("Muscle Rack" brand) and quickly realized the legs were going to severely damage my laminate flooring. I immediately came up with a simple solution by creating some custom feet using openscad to prevent scratches and add a bit of stability on hard surfaces. The design works perfectly when printed in flexible filament. It's highly customizable to fit any rack that uses an L-shaped steel rail. The default size is tailored for the cheap muscle brand rack I purchased (1.25 inches on each side). To ensure a snug fit, I used about 1mm tolerance on the length of the slot and 0.5mm for the slot width. Print Settings: Supports: No Resolution: 0.3mm Infill: 75% Notes: Fine layers are not necessary here. Use a high infill to prevent squishiness. Ninjaflex, semiflex, or generic TPU work great (I used Makergeeks' Maker Flex, which is as rigid as semiflex). I doubt this design would be effective with rigid filament, but if it does please share your experience in the comments.
