4040 extrusion endcap

I downloaded a few endcaps, but none fitted my 4040 aluminium profile, so i made my own.I printed it for my RatRig 750x800 workbench. You can simply change the tolerances in the fusion file if needed. I recommend to compare your profile to the one included in the CAD file first. The fit is snug, but it didn't take much force to fit.
