Bolt Pencil Case

thingiverse

Create a pencil case shaped like a bolt using 3D printing. After building an MK6 extruder, I found that rolling pencil cases were a common issue. To make it, print two ThreadedTube files, one BoltHead file, and one Nut file; skip OneThread for OpenSCAD use. Assemble the parts by screwing the tubes into the head and nut onto the open end of the other tube. Optionally, glue them in place for a 4-part pencil case. I initially faced issues with shallow thread sides causing overhang but adjusted the slope and uploaded revised STL files. The Nut and Bolt Head are now threaded as well. To print, adjust feed rate to prevent overhang strings (1.8) and reduce nut and bolt head fill to 20%. My daughter wanted it in blue; maybe I'll have a black one someday with silver-sprayed nut.
