Two very simple, diminutive accent parts for the Refyne EP1 bolt action pen.
I set out initially to make a simple sleeve cover for the M2.5x0.35 bolt screw head, as I've found it slightly uncomfortable to idly fidget with. While I was at it, I realized that the top cap has enough thread length to accommodate a slim color-accent washer.
The accent washer tightens securely under the cap's threading. The thumb stud cover may snap onto the screw but will be best held in with a tiny (tiny!) drop of CA glue.
I printed both from PETG with 0.1 mm layers.
