1 inch diameter dowel

This is a simple 1 inch diameter dowel for use with filament holders instead of wood. overall length is 450mm (17 ¾ inches). 

It's strong enough to support 6 rolls of filament with the supports at each end.

I designed it  to fit the end of my Printer cart :)

Make sure to print it with rafts as it'll tend to knock itself over with the bed movement. 2 sets are required for a filament support.
