VZ-Bot Frame Brace with 2020 profile

These are the VZ-Bot frame reinforcements made up of a 10 cm long 2020 profile and two parts molded in ABS.

for those who struggle to make very large abs prints or for those who simply don't have a print bed that's not big enough.
the thread must be made inside the profile cavity with an M5 male.
They serve:
2 M5 x 20mm screws;
4 M4 x 8mm screws;
2 M4 x 10mm screws;
6 M4 T-nuts.
I've always tried to make every weakness or defect of mine a strength, this is an example.
