Adapter from Humanscale monitor arm to Amscope microscope. The arm I use is M8 mk1, but it is set to minimum weight, which means the M2 is probably more than enough.

You will need:

• 1x M8 screw (min 35mm - max 50mm length) 
• 1x M8 nut

Assembly:

• Just insert the Amscope pole in place (fits from either side) and screw in place.
• Attach the piece to the Humanscale arm (snap in place)

Print instructions:

• Print standing up, should be fine in PLA or PETG, but I only tested ASA
