I printed it in PLA, probes with PETG on Prusa mini.
I make the mesh on top cover in Prusa Slicer. See this video tutorial from Prusa https://www.youtube.com/watch?v=6PVeh43Or-g.
For mounting you will need 7x M3 thread inserts and 1x 28mm M3 screw, 2x 19mm M3 screw, 4x 9mm M3 screw. See the photos.
Operational voltage of this type spot welder is between 7-16V and operational current is 100A-250A. I use 4s battery from my FPV drone, i charge the battery only to max 4V per cell (4x4=16V). I use two 4S batteries ( must be 2 identical battery with same voltage !!!) each 4S, 75C, 1600mAh ) connected in parallel, it gives me discharge current 240A and best results. It works too with one 4S battery (4S, 100C, 1550mAh), it gives 155A, but the battery gets quickly hot.
