The file 'DRZ400 Under-bar Mirror Mounts (for 7/8″ Bars) 3D Printer Model' is (stl) file type, size is 312.8KB.
I bought some cheap bar-end mirrors with the intention of mounting them under the handlebars but there wasn't enough movement in the ball-joint.
I designed these to fix that problem, it uses just a single M5 bolt and nut - I used the longer of the two that the mirrors existing clamp part used.
Designed for 7/8" bars, let me know if you want any other sizes adding and I'll upload a modified version.
