I had too many different spools of wire and solder on different sizes of spools.

I created this to help combat that problem.

Enter the demisions of the spool - outside diameter of the spool the inside diameter and the width of the spool, always give a little for ease of fit. i.e. if the width of the spool is 20 enter 21, use a smaller Inside diameter for the Pegs. And the length of the peg for adjusting for secure hold or ease of removal and insertion

Many parameters are adjustable i.e. size of wire, the wall thickness. Set to a multiple of your print head size - .6mm nozzle- set the line width to 2.4, using two permiters.

The qty of holders will create a gang of holders print the entire project and select keep as a single part.

Use a screw to hold it to where you need it. - the size of the screw is also adjustable.

Place the side with the wire guide on the build plate, and no supports are needed.
