Ryobi Battery Cap - Remix

thingiverse

This is a modified version of the Battery power supply cap. I found this design after starting my own battery cap, and instead decided to modify it. The model was edited to enlarge the area for metal clips. However, when I printed them, they did not quite align. To fix this issue, the metal clips were made extra large, allowing some room to move them forward or backward to adjust the fit. To get the correct fit, an asymmetric scale had to be used. The model was scaled up to 105% in all directions except for the width between the clips, which was increased to 105.5%. This adjustment gave a bit more space between the metal clips. Referring to the rounded end as the front, the final measured dimensions are: Inside side to side - 28.1mm (measured at center of metal clips) Inside front to back - 33.5mm (measured at center of arch) Outside top to bottom - 31.5mm (measured in several places) Possible changes could be made by deepening the recessed lip where the metal clips sit, which might slightly improve their fit.
