I designed this spool for the v4 haptic glove for LucidVR gloves as the original v4 haptic spools often had difficulty printing due to the thin wall of the spool. I have not tested these spools so use at your own risk. I take no responsibility for damages to your hardware caused by this design.
The other 3d printed parts, necessary hardware, and documentation can be found here: https://github.com/LucidVR/lucidgloves.
