M5 T-NUT FOR 4020 EXTRUSION PROFILES

Had many problems finding appropriate T-nut as my aluminium profile was slightly different from standard one used in AM8 kits. The only nut I've found is a M5 low profile nut. With my printed support you can make 120 T-nut for the cost of a metal one. thus making the whole AM8 project cost cut in a half. Enjoy it!
