WOWSTICK 1F+ 18650 Battery upgrade

thingiverse

The original battery of my Wowstick 1F+ was getting weak after some years of use. Instead of trying to find a replacement, I decided to upgrade it to a standard 18650 LI-ion battery. Parts needed: 18650 Li-ion cell 4056 Type-c Battery Charger Module 24 AWG wire Bolt: M3*10 Printed with PETG, in upright position, layer height: 0.2, without support On the photos you can see an empty hole on the front of the handle, this was designed to bolt the original and the printed handle together, but in my case it fits very tight, therefore it was not necessary. (maybe it depends of the accuracy of the printer)
