Simple holder for deburringtool, inside diameter 12 mm.

Printed first in PLA, but it broke too easy when screwing to the wall, changed PETG and all good. I printed with 0.28 layer.

Will work also as a pencil holder

NOTE! If you're using Temu type of deburring tool, it is littlebit bigger (diameter about 14mm). Then scale this up 25 - 30%, and it should fit
