This is a spool holder designed for the 3D Printing Nerd Design Challenge and features the 3D Printing Nerd's signature #High Five on the end and name on the top.

The bracket is designed to slip over the 1"x2" wherever you want and is low profile enough to not disturb the rolls on the shelf. The cutouts in the back are made to go over your shelf brackets so you can hang the holder anywhere on the shelves. The holes on the front were designed to fit #8 wood screws so you could attach the holder to the shelf more permanently if you so wish to. The rod on the holder should fit most 1kg spools.

From my test print on my Prusa i3 mk2s the print should take about 4 hours at a 0.2mm layer height and requires minimal supports.

This has been a fun challenge to design for and I thank you for your consideration.
