8020 1010 endcap

For use with 8020's 1010 aluminum extrusion profile. Requires you to tap the central hole of the profile for 1/4-20 hardware. It takes a bit of elbow grease, but it's absolutely worth it. For this particular project, the bolts stuck out a little to allow the mounting of a sheet of plexiglass.

It makes use of a sacrificial bridge, the single greatest piece of advice I ever received about 3D printing, courtesy of [Hackaday](https://hackaday.com/2017/10/17/sacrificial-bridge-avoids-3d-printed-supports/). This allows it to be printed right-side up without any supports. Originally, I printed it with the top down, but not all of my printers could handle the gentle slope of the fillet. The only headache is clearing away the little strands of filament criss-crossing the hole.
