Simple spool holder/stand using four 608zz (7mm x 8mm x 22mm) bearings. UPDATED: added a bit more space between bearing and bottom and reduced the chamfer size.
I designed the stand with reference to a spool with a diameter of 200mm, but it should work for other spools as well.
I added some grooves at the bottom for easy removal and some fins (feet) for improved stability. Obviously, you need four bearings, four pins, and two holders, which should snap into each other pretty tightly. If necessary, a touch of super glue won't hurt.
This is intended to be an entry-level design project for students to learn about basic sketching, constraints, patterns, projection, extrusion, tolerances, etc.

STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.
When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides: http://www.nsta.org/safety/.
