cover for #2 size X-acto knife (11mm, 7/16 in diameter handle)

I needed an x-acto cover to print in bulk and I couldn't find any designs I liked that fit the larger handles for #2 blades. These will fit handles with 11.2mm-ish (7/16"ish) collars.

I like this design because:

• it prints quick
• no support needed
• stops knives from rolling off the table without much added bulk
• easy to tell which direction the blade goes
• snug but easy to remove from blade

I printed these in PLA on a Bambu P1P with standard .2mm profile.

Since I made these for work I designed it and shared it via our Tinkercad account. Check it out and remix it here: https://www.tinkercad.com/things/42kohJ2KSA4
