Electrode holder Mini Spotwelder (red one)
thingiverse
Holder for sportwelder electrodes to keep the same distance between the electrodes For the Red DIY minispotwelder (aliexpress) Distances about 5mm. Maybe you need to modify it a little after printing. Changing diameter. Taking of the heatshrink of the electrodes gives more margin. Or scale the stl file to adjust. Threat M3/M4 ABS recommended. P.s. this spotwelder needs some modifications to work properly and life extended. User Luca on Youtube https://www.youtube.com/watch?v=RSrlXqFxhp8 I'm using this with 2x 3s 1300/75C lipo (parallel)
