I designed this to convert things other than masterforce to a masterforce battery to be powered. So i have a one battery fits all around my house. I can use this for things that i make like RC cars, and for powering my Raspberry pi or Arduino; or to store power in a vehicle while i swap batteries so i don't have to enter my presets or factory code. it is just a nice handy portable power!!!

print this bottom up so the parts that meet the battery are printed on top.

I had to measure the battery and drill in much more detail than i thought at first. I never expected to spend as much time as i did to come up with this design. But with my trusty ol diocaliper i got it figured out. once i had the dimensions i went on tinkercad and made it. I printed one test, made some adjustments and on the second print it was good to go!!

I used an 8/32 nut in the base.

I used sheet metal for the terminals; I cut it to size with tin snips and soldered wires to them before i put them in so that i didn't melt the plastic.

I also fused the wire coming off the battery to protect the circuit board within the battery
