clamp for mechanical pencil + stick eraser

thingiverse

I use this because good mechanical pencils have overly optimistic tiny erasers which are next to useless. So far this clamp holds them solidly and isn't awkward to write with if held in the right way. I'm using Uni Mechanical Pencil Kurutoga Pipe Slide Model 0.5mm and Pentel ZE21BP3K6 Clic Eraser, available at http://a.co/0bkRPcd and http://a.co/7UlK7HE. The outer barrel diameters of the pencil and stick eraser holder are 10.3 and 10.1mm, and the clamp adjusts accordingly to negative space, so it isn't completely symmetrical, although PLA is pliable enough where it probably doesn't matter. Print settings are very straightforward; you can pretty much max out layer height because it's basically a 2D shape extruded into the Z-axis.
