Mingda Magician Pro/X 3kg Spool Holder

Here is a pair of 3d printed uprights to hold more 1kg spools OR a 3kg spool. It is designed to use a 1 1/8" or 28mm wooden dowel. Two uprights are required, just download the single model and mirror it for the second. 

Thank you to those who posted makes for the Magician X confirming that it works on that platform as well!
