Description
My hobby knife sheaf broke, and I needed a cover for the cutting blade. So I designed a lightsaber cap so it can stand upright and look cool while stored safely.
There are two models, one with a “switch” and one without. The “switch” is a magnet that will help hold the knife in the cap while giving the cap a cool look.
I designed this for an 8mm knife handle with a #11 blade.
If you should choose the non-switch version, you'll need a well calibrated printer. The holes is 8.1mm and should have a friction fit with the knurled pattern on the tip of the handle that exists on most knives.
The “switch” is a 6mm magnet. I suggest using either a 2mm or 3mm thick one. Here are two sources:

I've used this model for both the off-brand handles, and for Xacto branded knives. Here are some cheap handles that should work without issue:

I would suggest to print in PLA or PETG and a minimum of 2 walls, 15% infill. You can print it upside down or right side up, but both require supports. I would suggest organic, on build-plate only.
