This is a charging dock for HTC's Vive Tracker pucks. I've modeled this to perfectly form-fit the trackers, using HTC's own CAD files as a dimension reference.
I've followed SG-O's standard on the cord inserts. (As seen in his thing here) I've only included the custom usb cord inserts for the stock Vive USB cords. But if you have another type that works with SG-O's inserts you can just use those. Either will work with this design, just those aren't going to be as form hugging since they were made for the controllers.

Pictured with my chargers is the remix for SG-O's chargers by abcdqfr, from here.

HTC's CAD files for the tracker can be found on their developer page for the trackers here. Direct download here.
