Stanley Battery adapter (FMC688L FMC687L)

thingiverse

Battery adapter for Stanley Fatmax 18V batteries (battery models FMC688L, FMC687L). Originally modeled for use in [Adam Savage's soldering station](https://www.youtube.com/watch?v=8uGS11yuVyo) and as a holder for spare batteries. Parts modelled in Fusion 360 (model attached) - due to the overhangs it is recommended to print the two parts separately and then glue them together with a cyanoacrylate/crazy glue. For contacts I used the male faston tabs (6.3mm width): first I soldered wires to them, then I heated them with the soldering iron and pushed them through the slits in the holder. I did not crimp the connectors to leave them as wide as possible for better support in the plastic. To further secure their position, I added also some two-part epoxy to the base of the tabs (just a few drops with a toothpick), but it might be redundant, as the connectors held in the molten plastic quite well even without the epoxy.
