This is a great little utility knife, I printed eight of these and gave them out to friends and they all absolutely loved them! However, the clip piece is prone to breaking towards the top of the clip. I suspect that a little bit of reinforcement added to that part would solve the issue. I do also wish that the spring release was on the back instead of on the sides so it could be manipulated with the thumb. This is very very close to being a 10/10 print, it's probably a 9/10 at the moment!

Overall it’s a good model, however the tape roll tends to pull up and out of its slot easily. A retainer of some kind would make this a 10/10 print!
