i have a spare FeiyuTech Mini 3D Gimball for a drone, so i decided to make a hand gimball.
A hand Gimball cost a lot, this gimball cost 100€, and you just need a battery like a lipo 2s or 3s. I used 4 AA new technology 1.5V rechargeable, normaly you need 7V in total but it works with 6V.
No glue, no screw, just the "attaches" part that block the gimball frame ;)
50% infill for support, 30% for couvercle and 70% for attaches
