DISCLAIMER

The knife inserting system damages the blade apex and may make the paper difficult to cut.

Please consider my Version 2 with a reworked knife inserting mechanism that does not involve touching the edge.

================================================================

Idea taken from an Aliexpress product, recreated for 3d printing I also slightly scaled up the model to fit some larger-than-standard rolls. Max is 45mm

Hardware: 
1x new craft knife blade (number 11)


Best results with a smaller nozzle.

Take caution when inserting the knife. It is press-fit, and requires a little bit of force to push it in all the way. I used some thin needle-nose pliers to get it in without pushing on the blade. Since making this, i have also uploaded a tool to safely and easily insert the blade.
