Ikea pencil extensioner with variable width

I really liked the idea of this extension, but the pencils I have didn't fit tightly. So I created a remix in which the hexagon changes its width from 71 mm at the ends to 67 mm in the middle and now the pencils stay stable.

0.20 mm layer height
0.40 mm nozzle
100% infill
It's a good idea to use a brim.
