Kyosho Mad Force USA-1 Mad Crusher FO-XX FOXX Diff Locker

This is my simple differntial locker I made for my Kyosho trucks. It will fit the Mad Force, Mad Crusher, FO-XX, Mad Force Kruiser or any other Kyosho product that uses the IF103/103B differential case/cup housing like the Neo buggies. I run the rear locked in my USA-1 and the front open, works well for my liking.

The locker only fits properly in one orientation. I printed mine out of PETG and its held up really well but PLA or PETG plus will probably flex less. Super easy and fast print so use whatever filament ya have except probably silk PLA. 2 walls and 20-30% infill should do you fine but I printed mine solid since its such a small part and printed quick as is.
