The Staedtler 925 is a great mechanical pencil but the permanently protruding lead sleeve makes it difficult to clip in a bag or a pocket.
A couple of minutes in Fusion 360 and 9 minutes printing - problem solved!
Prints fine in PLA. 0.2mm layers, 2 perimeters, 15% gyroid infill. Closed end on bed.
