DIY 2170 6S Holder

thingiverse

Use these files to make yourself a DIY 2170 battery for long range drone flying etc. These holders provide better electrical isolation over directly gluing the cells together (risk of a short circuit if the cell cans touch together in a crash!) 2170 6S Holder.stl Slicer settings: - Use PLA+/Nylon or other solid but slightly malleable material (NOT ABS/PETG as they fracture on failure). TPU should be fine if you're happy to have a bit of cell movement - 0.4mm wall thickness - Infill 0% - Properly calibrated flow/extrusion multiplier for EXCELLENT layer adhesion - Properly calibrated linear advance Result: single walled print 'vase like' with no layer separation. Clean up any imperfections on the insides the holes with a knife/file/sandpaper to get as close to circular as possible - adjust print scale to get as close as possible to a 'snug fit' on the 2170's. For a single wall thickness they're surprisingly strong, especially if you scale them vertically, but I won't guarantee they'll survive a crash, cinematic flying only! 2170 6S Cap Bottom/Top.stl - These are not necessary but they make the finished pack look more professional :) - Print with your default slicer settings - Scale for a light press fit - Can also print with PLA+ etc but I recommend TPU for some impact absorption - I recommend applying a some silicone sealant to the top of the cells to hold the caps on. Cover with 120mm FLAT WIDTH PVC heat shrink to hold everything together. Enjoy!
