Scrap Copper Wire Stripper Block

thingiverse

Update: 7/25/19 Removed excess part for easier loading and pulling. Made it more printer/material friendly by shortening the path for the wire to get to the blade. Added two new 3.5mm diameter through holes in the bottom and rear to better support the assembled structure. We found a large pile of stranded copper wire in a scrap pile, with an outer diameter of around 3.2mm. We decided to start stripping the sheathing and recycle the copper. However, if you don't have a machine to strip wire, it gets tedious and painful. We tried wedging razors in wood with a hole drilled through to guide the wire, but with limited success. The blade kept getting out of position causing more repair than stripping. I came in and opened TinkerCad to put in some work. I'm really novice at modeling, and I haven't printed it yet. Assembly Notes: It will require M3 machine screws and matching nuts to assemble. Once you lay the razor in the recess in block A, mate block B to it, insert M3 machine screws in all holes and tighten the nuts with washers. Do not use the forward top or bottom screw holes if you plan to use the mounting block. Screw the mounting block down to a workbench or surface with the two through holes on either side. Then insert a longer M3 screw through the through holes in the top of the mount, through the two blocks. This will secure it all together. If you don't want to use the bench mount, just insert all screws and tighten accordingly. I apologize if this isn't perfect, it is a work in progress! The reason for the seemingly excessive amount of through holes for M3 screws around the blade recess is to keep the blade from slipping between the blocks, out of the recess during extended use or strain. I recommend three walls (perimeters) because when in use, it will be under a lot of flex and strain.
