The file 'Vivedino Formbot T-Rex 3.0 Endstop Precision Upgrade 3D Printer Model' is (stl) file type, size is 215.8KB.
Endstops with pushbutton switches and metal lever are not precise. Lever gets loose and falls out eventually.
On named 3d printed endstops design is also faulty. Switch gets bent and twisted on pcb.
I created standoffs to hold switches tight and pusher to eliminate switch lever.
Just mount them with stock screws as shown.
By the way i had to modify T1 offset to 0 after this upgrade.
