If you want a printing method that is easy to maintain, you can consider my redesign:

update 01/12/2024
This knife is a one-piece printed design. If you are not sure whether the filament you bought can print this work well, you can refer to my new creation "Nichirin Samurai Sword". This work uses a split printing design to facilitate future maintenance and blade replacement.

Reverse Blade Sword mini
This is a smaller version of the Reverse Blade Sword, with a total length of about 80cm, suitable for A1 mini printers or people who don’t want to print too much. If you want to experience the full size, please go to https://makerworld.com/en/models/111322
Notice
It is recommended to use PLA+ and Textured PEI Plate for printing.
If the viscosity of the plate of your 3D printer deteriorates, be sure to use glue to increase the grip to prevent the printed part from falling off halfway and wasting filament.
After printing, please remove the support at the end of the knife.

Repair of fallen blades
This work has been printed and verified on P1S, A1, and A1 mini printers and resized. It is currently tested using three materials: Bambu PLA, eSUN PLA+, and eSUN ePLA-Matte.
The blade surface can be freely expanded and contracted without falling off.
However, since PLA material is not resistant to high temperatures, if it is stretched and swung back and forth many times quickly, it will cause the blade to be heated and expand, causing the blade to be thrown out.
At this time, you can repair it with a simple method. Please use a tape with high viscosity that is not easy to fall off, such as Acetate Cloth Tape.
Stick it on the entrance where the blade falls off. The amount of tape can be adjusted to increase or decrease the size of the enlarged hole. Then push the blade down and plug it back into the entrance to repair it.
