CR-10 reinforcement angle/brace

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4543759.

I designed this, so it can be printed on the Ender 3 as well (because my modded Ender 3 is simply much quieter). It uses 8 M3 T-nuts and screws (use at least 8mm long ones, 10mm are most likely easier to install)
