X-Acto Knife Cover

X-acto knife cover for X-ACTO X3290. Has spiral grip for easy removal. Can be printed without supports. May fit other X-Acto knife handles with similar knurled grip. Use 100% infill or enough walls to make the print solid. I used PETG for strength and flexibility but you may use PLA, I'm just not sure how well it will hold it's grip after a repeated use.

Make sure to print with a brim of at least 5 passes to make sure there's good bed adhesion.
