This tonfa-shaped keychain is becoming very popular; it is priced at €25 online, which seemed a bit excessive to me, so I designed and 3D printed it in PLA.
It is used for self-defense due to its maneuverability and the fact that it doesn't cause harm.
For convenience, I divided it into two parts and created grooves; this way, the two halves can be glued together, with the adhesive filling the grooves.
I printed it in black PLA, with 100% infill using lines. Length of the model as is: 14cm
