3D Printing Material Spool (for samples)

thingiverse

I created this custom laser-cuttable spool holder to store samples of various 3D printing materials I've acquired at trade shows and online purchases. The diameter is 150mm, which is noticeably smaller than a standard spool. Its inside hole measures 50mm in diameter, with each unit consisting of six distinct components: two circular sides and four rectangular connecting pieces. This unique design can be assembled using either superglue or wood glue, depending on the desired outcome. It boasts strategically placed holes on both the outer and inner edges to secure the material at each end, as well as a horizontal slit that allows you to visually monitor the remaining material level, much like a conventional spool. This innovative spool is designed specifically for cutting from 3mm plywood, as seen in the accompanying images.
