Design:

Based on Gridfinity Refined and compatible with all Gridfinity spec baseplates.

Meant for storing NP-F550/570 batteries. The fit is fairly snug, as the batteries are tall and I don't want them to rattle.

Print Settings:

No special print settings are needed. I printed on a Prusa MK4S in PLA at 0.25mm with 15% infill. Lightning infill pattern works fine if you want to save some time.
