I use this for my 3D printer enclosures - sometimes you want to open the door and get it out of the way.
The mounting holes are for “6 gauge” or 4mm countersunk screws, the pivot is M4x30 cap screw (if you get a longer one with an un-threaded shaft portion and cut it down, it's even better).
Designed for 3D printing, not mimicking a metal or injection moulded part. Print in the orientation it loads in, no supports, minor overhangs.
The author marked this model as their own original creation.
