About this 3D model

Version 3 is released, please check https://makerworld.com/ja/models/1409354-collapsible-katana-revoluted-v3 Inspired by https://www.printables.com/model/442829-collapsible-katana-v2/files --------------------- My kids are big fans of the collapsible swords. I have made tens of models for them. Since the blades are easy to drop and relatively weak, and in addition, the original model is a glued up model, It is easily got broken and each time I have make a whole new one for them, much of waste. So I decided to make my own one to address the issues, by introducing a rubber ring tensioned blade lock and disassemble structure for exchanging the blades. Also, considering the rubber ring might break in the future, I added an anchor structure that make the rubber ring could be exchanged from outside. To drag the rubber ring easily, a puller tool is also included into the 3mf file. The assembly guide is listed in the thumbnails and not very hard to assemble. Have fun! ------------------ Updated on 2023/11/03 The folding diameter of the rubber ring is 60mm, please check out the thumbnail for reference. As the holes in Handle and connector are built w/o support, the diameter of the hole is not as perfect as other surfaces. This could cause the filament being hard to insert. I recommend to use a Hex Key T1.5 to clean the hole, then it will be much easier.
