I was in need of a scribing tool on the last set of shelves, so I made this one before I finish the next set going in.
This simple scribing tool has two ends to help scribe various surfaces:
- The ball bearing end is made for flatter, less detailed surfaces. It is designed for an 8x19x7mm or 8x22x7mm bearing. You will need to use a bit of force to get the bearing on. (I've printed four of these and didn't have any issues with it breaking.)
- The pointed end is made for more detailed surfaces like stone or brick or trim.
It fits most common #2 or color pencils you would find around your house.
I chose to print the scribing tool in HTPLA or PETG. The pencil holder on the inside of the tool is printed in TPU. The TPU allows for enough flex so that when the pencil is inserted, it semi-locks both the pencil and holder in place. It's not perfect, but it gets the job done.
