Bosch 18V Battery to XT60 Adapter - with CAD

This is a remix from the Functional Print Friday's Youtube channel of a cordless battery adapter for a Pinecil soldering iron.

Mostly, It includes an XT60 connector built into the part to make it a little more universal, making it a little neater. I've changed the way the adaptor connects to the battery using PCB mount blade connectors and a small strip of Vero-board shaped to size. It's very rigid and makes for an easier assembly process than trying to cut strips of sheet steel to use as contacts.

Lastly, I changed from using M3 nuts to heatset inserts (M3,4L,5D) to make assembly a little less fiddly. You'll see there's nice big scallops in the rail of the battery adapter to clear the tip of a soldering iron so the headsets can be inserted from the bottom. This prevents the heatset inserts from being pulled out of the plastic

I've included step files converted and cleaned up from the original STL's

Print the files in the orientation of the STL's; You'll need supports on the battery interface and possibly on the areas where the connector and wires go. The fit of the XT60 connector is pretty snug, but I suggest a dab of CA glue to keep it in place on the battery interface model. Obviously you should not use glue on both top and bottom cavities. I've used M3 x12 button head cap screws - the exact length is important so as not to interfere with the battery
