Protect A Threaded End During Transport

Round Cup / Cap

An open round cup you size yourself. Print it short and it is a cap; print it tall and it is a cup or sleeve. Stand it on a bench to corral fasteners, bits or pens, cover a pipe or post, drop it into a recess as a liner, or slide it over a post as a deep sleeve. Set the outer diameter, wall thickness and height; each one is engraved with its own dimensions.
