A solution to the "I need to change my battery but the ground dirty" This adaptor replaces the Pin-back cover, and adds an extension for your lanyard to clip into.
Properties:
I have attached pictures of printing orientation and where supports are needed.
NOTE. Make sure there are no supports generated inside the slots.
I had the best luck printing it in the orientation provided as the bridging properties worked in favour of the less detail critical areas.
Support:
If you appreciate the design and want to help me out with my University fees any donations are welcome. :-)
