Ryobi battery plug

thingiverse

I made this to make my own DC to AC inverter to use with my Ryobi batteries. This has the potential to be a part of any DIY project needing a moderate performance, rechargeable 18v battery. I left screw holes in the base plate for the future option of some sort of housing to contain mount/components. My next plan is to implement a PWM controller between the battery and the Ryobi angle grinder so I don't have to buy a low RPM or variable speed model for polishing stone. You only need supports for the small tabs that the battery grabs once locked in place. Personally, I print with a 0.4mm nozzle, at a 0.18mm layer resolution, while combining infill every 2 layers, 2 perimeters, 20% infill. Your preferences may vary. If your printer doesn't print bridges well, then you may need supports on both parts. The full assembly needs 2 parts printed. I provided a model with both parts oriented properly for printing. You could glue them together, but they seem to stay together just fine without. For the positive and negative terminals, I simply left a slot to fish some wire through and wrap around. With a battery inserted the wire should press against the terminals. I will use metal tabs for higher amp applications, but the wire wrapping works for smaller loads.
