Daiko Ceiling Fan Remote Control Battery Cover
Battery cover for DAIKO brand RC ceiling fan. Does not fit as well as original part, but should lightly click in with ease.
Part contains thin walls, handle with care when taking off print bed ;-;
I recommend printing with brim, sideways as shown in the screenshot.
Printing vertically didn't work very well in my case due to lower layer adhesion strength. Printing horizontally, facing up can work but will usually result in lower surface quality on the backside of the cover.
