This is an adjustable mounting bracket for the Koonlung K1S Dashcam LCD Monitor, and is designed to fit the mounting clip supplied with the K1S LCD unit (the LCD just slots onto this bracket, for easy fitting/removal). The base is 60mm diameter and can be fixed using 2mm double-sided tape (for example: 3M 9448A). It allows for tilt adjustment on two axes (elevation and roll) so that you can level the LCD, even on a sloping dash.
Requires 2x M3 countersunk screws and nuts to assemble the three parts. In my case, I added double sided tape between the parts before tightening the screws, to semi-permanently fix it at the right angle.
I've since tidied up the wiring with some 90 degree right-angle micro USB extension cables.
Obviously this gets subjected to extremes of temperature in a car window, so it's probably best to print in ABS rather than PLA.
