I'm building an enclosure based on Jure Korber's https://www.thingiverse.com/thing:2792618 but decided to make it in 2020 Aluminium Extrusion instead of 3030
I wanted a set of adjustable feet for levelling the printer enclosure but couldn't find any.
Post printing the threads were a bit tight, so I ran an M8 tap through the end caps and the fit was perfect.
This version is for those who want to screw the feet to the frame instead of relying on a press fit.
Note: Print the screw with 100% infill
