xacto knife cap

Prints properly (enough) with 0.2mm layer, as oriented.

The cap fits knife with 8.0mm diameter holder (8.3mm diameter knurling).  The first few cappings are tight, but it smooths out with a nice “click”.

When capping/removing, hold where the “through-holes” for a better grip and to avoid the blade. Don't stab yourself. (I haven't yet, but it's bound to happen soon.)
