Hardware required:
This was designed around American 4AWG wire specifically and the Stanley utility knife blade, with the intention to make it somewhat usable on some smaller wire. Blade depth is adjustable with the longer M3 screw.
Photo is from an older iteration of the design. I haven't printed the current model, yet. Let me know what needs improvement. I never had an intention for this to replace a proper wire stripper, but didn't want to wait on an order for a proper wire stripper.
