wanted to mount my dash cam behind the rear mirror but there are these black dot sun block thingies and the suction cup mount wouldn't hold so i decided to glue it dow. 

slap a slap 3M Adhesive tape on it and glue it down 

don't use PLA, use heat resistant filament... at least petg or better asa/ABS

it's meant for abask J05 Dashcam but it should fit other cams as well

Distance between the bracket 12.9mm
