A battery holder for 21700 li-ion cells with 25x25mm mounting holes. Perfect for lightweight long range builds, 3 inch, crux3 etc.
Print this 21700 Battery Holder in TPU and use supports as shown in the photos to support the overhangs and also stop it from flexing as it prints the higher layers.
Please note that the inner diameter of the holder is enlarged slightly to 21.5mm to allow for the additional black heat shrink tubing and the negative wire that runs down the length of the battery which increases the outer diameter.
