A more ergonomic version of SmileyPrinter's TikTok bolt-action fidget toy. There's a version with and without speed holes.
Requires 7 6mm x 3mm circular neodymium magnets (ex https://www.amazon.com/gp/product/B096LZNZTQ). Included SmileyPrinter's diagram of orientation for reference.
I advise printing the bolt core (13mmErgoCore) horizontally with support and shaving/sanding until smooth for added rigidity, though this is not required. I would also advise printing the main body on the flat, diagonal surface at the rear of the toy with tree supports enabled @25 degrees, or enough so that some get generated at the front/top threads.
The author remixed this model.
I loved the TikTok Bolt Action Fidget Toy posted by SmileyPrinter but wished it felt better in the hand. This version includes the more ergonomic design in addition to a slightly larger bolt and thicker, stubbier bolt handle to avoid breakage.
