Ratchet Mechanism First Study
This is one of the first models in a series of simple ratchet mechanisms. To test their strength and functionality, it was included in the design an hexagonal slot for the standard 1/4" (6,4 mm) bits. It holds force quite well, however it needs some force to rotate the pawls. This model was published on Thingiverse ( https://www.thingiverse.com/thing:2213785) The shaft has a conical design to allow printing in one piece (although in this case it had to be separated in two), act as a bearing and hold some axial force. For future projects, already in tests, the ratchet mechanism will be printed in one single piece.
