Cap for 8mm blade pen

It is a simple cover for the crafting knife.  The crafting knife comes with its own blade protector, but over time you may lose it.  If that is the case you can print this one. 

The slicer will advice you to use a brim.  I advice you not to do that.  During my testing I notice the brim reduces the width of the cap and makes the fit too tight.  Instead, just use some glue stick even if it is PEI sheet.
