My kids like Sdvalentones Bullet Bill / Banzai Bill very much, but they wanted hands for it.
So I found some hands in jamesglanville Bullet Bill model, took them, fused the halves together in Tinkercad, enlarged them and put them on cylindric stand. As a reference I used Bullet Bill Keychain by bas in the beginning, but at the end did not try to position the hands properly (sorry, Mario purists…).
Hands are printed with supports, oriented so that layer direction is paralell to the highest load.
Hands are printed with PLA and glued to unmodified Banzai Bill body using Chemoprén na obuv (which seems to be a local variant of Pattex Contact Adhesive All Purpose Transparent glue). (I use it to bond PLA almost exclusively).
For those interested in modifying I published the Tinkercad projekt here:
Correct placement (ie as by this comment: https://www.printables.com/cs/model/347114-bullet-bill-banzai-bill/comments/1092373) should be easy
The author remixed this model.
Hands from jamesglanville Bullet Bill model are enlarged, fused, trimmed and put on stand to fit the Sdvalentones Banzai Bill (unmodified) model.
