My wife bought me a Pebble Time Round smart watch. Pebble as a company is gone but there is a large community that still supports it. I bought an extra charger and didnt read too closely about which models it supported... unfortunately, mine wasn't and it wouldnt connect.

Looking closer, I realized it was the casing rather than the electronics that didnt fit. So I designed a new casing that would hold the electronics and should work with any Pebble watch that has this charger pad.

The charger (wrong) that I bought:

I removed the rubber foot ring and reused it on the bottom of my design. The rest of the plastic housing was discarded. I hot glued a large steel washer in to the inside of the base to add weight and stability.

Desolder the red and black wires to either wire direct, or in my case, I soldered some red and black hookup wire, fished it through the riser and connected to charger wires and hot glued the rubber strain relief in to the entry hole.

After printing, I sanded and painted mine...
