Century/Craftsman/Snap-On/Matco/NAPA Battery Charger Mode Switch Fix

Quick fix for stripped mode switch shaft (likely a common issue) on a gift/non-working 27 year old battery charger (to avoid purchasing a generic high-dollar Asian replacement switch). 3D printed from PLA and installed with 1/4 in. fasteners and 5/16 in. flat washers with switch secured inside bracket with hot-snot. It was installed slightly rotated to one side so that the selector knob pointer lines up with selections on front panel. An externally accessible glass fuse holder and 15A slow-blow fuse were also added.Most of these old chargers (as long as transformer isn't toast) only require replacement of button diodes/plate and/or switches. Two or more 100A diodes in parallel on a suitable heatsink (not the original steel plate) can replace the original diodes/plate.This fix should apply to various/similar Century, Snap-On, Matco, NAPA, Schumacher, Sears, DieHard, Exide, Interstate, Midtronics, Goodwrench, Cornwell, DEKA, CarQuest, Delco, John Deere, Solar, Dayton, Goodall, Canadian Tire, and Ultra Pro battery chargers (and probably many others).Not a hack as it's stronger/better than what originally secured the switch :)
