Made this for a friend, but I thought others might benefit, too.
It's a nice snug bolt protector for a Lawton 7500 bolt. The end is a screw cap for easy cleaning.
The edges are rounded so you don't cut yourself up on them.
It requires a little bit of support, but it's pretty easy to remove with a knife.
I've set it to be it's relatively snug, but using an interface material it could be made very nice indeed.
The 3mf file was created in Bambu Studio, for an X1C and PLA, no support material.
