Summary

Modular Thread Spool Holder

This is a modular spool holder for 5 cm. diameter thread spools.
You decide the number of rows and columns for the grid.
Follow the formulas in the pdf document to calculate the number of parts.

First test 1 base module, 1 connector and 1 pin to test your printerstolerance and settings.
The pin will friction-fit in the middle of the base.
The connectors need to be glued. I did not use CA 'super' glue.
I prefer PVC glue (also used to glue pipes and fittings)

Enjoy!
