Hello,

"I based this on the great model from @emkatech and adapted it for Martor No. 52 blades. I added a honeycomb pattern to the handle for better design , and designed a flexible TPU safety cap.

The model consists of:

• handle,

• blade retention piece (pièce de maintien de la lame),

• nut 

Printed support-free in PLA at 0.15 mm layer height with 20% infill.

• TPU protective cap => I got a very good result with TPU 95A, printed standing up with supports, layer height 0.20 mm. (see photo for the orientation/position)

You'll need:

• 1× M4×16 screw,

• 1× M4 nut,

• Martor No. 52 blades  (amazon...)

I think PETG would be perfect for added strength and durability.

Happy printing.
