1. Introduction:

1. Four versions: mini, mini+, medium, and large + a comb version (added based on comment requests), compact, and less time-consuming; the mini version only takes about half an hour

2. No other parts needed besides 3D filament, use filament as the axle to connect the handle and blade

Other parts needed besides 3D filament: No

3. Assembly Method:

use 3D printing filament as the pin.

4. Tips:

1. Solution for the blade getting stuck inside the handle and not rotating smoothly:

1. Use a print profile with a larger clearance, increasing the gap between the handle and blade by 0.2mm to prevent sticking

2. As shown in the figure below, scale the blade's Z-axis dimension, changing the size from 4mm to 3.8mm or smaller

Note: Do not change the XY dimensions

2. The parts are small and the features are even smaller, the first layer is prone to failure, please reduce speed for the first layer

3. Inserting the filament into the handle may require some force, this is for a secure fit. The flow rate will affect the size of the holes, which in turn affects how easily the filament can be inserted, please ensure proper flow calibration

5. Recommended Print in Place butterfly knife version, easier to print, no supports needed.
