Description
Bolt Action Mini - Keychain Fidget The Bolt Action Mini Fidget is a compact version of my original design: Bolt Action Fidget . I redesigned it from scratch to be smaller and more compact for everyday carrying and fidgeting wherever you may be. The mechanism works the same way as the original, a satisfying bolt-action fidget reminiscent of the action on a rifle, but is has been made smaller and includes a keychain loop so it can be brought around anywhere. I've also included an optional bent handle for a more tactical feel, a low profile handle for easier one handed fidgeting, and a Loop-less version of the case. Printing: Everything is designed to be printed without supports, however some machines may need supports on the overhangs or extra bed adhesion to prevent parts from falling over during the print. I personally recommend printing with at least 3 walls and 20% infill at a .2 layer height. Printing time is around 1 hour for faster machines. Assembly: The fidget requires 3 parts that assemble together without the need of glue. Print a Case , Bolt , and Handle of your choice, or the all in one "Full" file. Slide the bolt into the case with the "M" logo on the bolt towards the back, opposite of the key-loop, and the small divot side closest to the "M" logo on the side of the case, the side with the key-loop. The handle then screws into the opening in the bolt at the forward position before locking the handle downwards in the cutout on the side. When properly assembled the bolt should be flush within the case when the handle is locked downwards in the side opening. Refer to the photos for the correct assembly.
