Inspired by AvE's design. This is a completely remodeled version and is not a derivative or a modified version of the original.
There are two versions depending on how you want the blade to stick out of the top.
You will need one M3 heat set insert and M3x8mm bolt for the blade retention lock.
The knob can be tightened in any position to lock the blade in place so it can't move in and out anymore.
Can be mirrored for a left-handed version
If the blade is tight sliding, put a drop of oil on the spine of the blade and run it up and down a couple of times.
I printed them in ABS at 100% infill and a 0.16 mm layer height with a brim
