Simple LiIon 18650 4S Battery Spacer

thingiverse

I required 18650 battery spacers to build a 4S LiIon pack for my S800 Sky Shadow Wing and fabricated a few from here which snap together, but unfortunately due to their shape the corners prevent me from closing the canopy on the Wing. My objective was simply to create a spacer tailored specifically for 4S from the outset so it wouldn't require extra material for the clips, and to round the corners so that it would fit smoothly inside this Wing. This design should work on other planes and Wings too and will maintain the battery pack size at its minimum. If you decide to print this I found that hot gluing the batteries into the holders works best for me and keeps the batteries in place without shifting about. If anyone has any suggestions for improvements feel free to message me. I might also create other sizes, such as 3S or 6S, etc.
