1020 Extrusion End Cap

thingiverse

We were making a benchtop shelf using some 8020 extrusions and I needed some end caps that would keep the legs from slipping on the bench. I came up with this design for our 1020 legs (1" x 2" extrusion) -- just print it out and press a #123 O-ring into the groove (EPDM o-rings are nice for this application). Secure it in place using the pins. update -- I improved the pin design so they look different than the ones in the photo.
