Performax Side Hook

I recently purchased a Performax heavy-duty shelving unit from Menards and was looking to capitalize on the storage space by creating hangers for the sides. I was unable to find any existing hooks that fit my specific shelving unit. These are very tight-fitting fitting and you may need to adjust the number of walls and the infill settings if you find that they break when installing. I made mine using PETG, but am assuming PLA would work if temperature is not an issue. I have not done any strength testing, so I am not sure what the weight limits are for this. Therefore, you should do weight testing before attempting to hang anything heavy from these hooks. I've only used them for light-weight items. I have included 4 sizes.
