Print a sew-on pocket for your lipoly battery! The pocket protects the battery from abuse and also makes it easy to remove the battery for charging. It's not strictly necessary, though, but bare lipoly batteries can be risky, so unless you protect it in some way, we recommend using a hard shell alkaline pack like the 3xAAA holder.

TPE Flexible Filament

The battery pocket works best when printed in flexible material like Ninjaflex or Semiflex. This material requires a direct-drive extruder system and can be challenging to print. We recommend Semiflex because it handles overhangs better than Ninjaflex, and has a shell hardness (98A). Follow the print settings below for best results.

Printing speed




Raft / Support Material


Extruder Temperature


Heated Bed

20-50c (if applicable)

The part should be centered on the print bed and ready to print "as-is". We recommend using CURA, or Simplify3D to slice the file.
