A safer bread lame?

If you are wary of handling razor blades for a bread lame, this may help. It requires minimum handling of the razor blade. The assembly sequence is shown in the main picture. To remove the blade, simply reverse steps F, G and H, basically using the holder to pop the blade off of the handle.

The blade holder needs the slot to be a firm fit and this will depend on individual printers and materials getting the slot precise. I lowered the print head slightly to get a slightly splayed first layer which holds the blade snugly.

UPDATE -

I have "upgraded" to a Bambu Lab printer and found that the fine slots aren't achievable on the X1C. It's probably a config setting but I was surprised to find the X1C couldn't resovle the print to the same resolution as my old Ender 3 V2 with mods. Shame I gave it away really... :(
