gridfinity spool holders

#gridfinity spool holders. Thread your wire (or whatever) through the hole and just pull it out when you need it. I find this easier to print and use than spool holders with axles.

Included are 2x3 blocks for:

• Standard 20x55mm wire spools
• Wider 34x55mm which fits most thiccboy solder spools

Parametric fusion 360 file Just specify the spool size and slots wide/deep and it will adjust automatically to fit the max number of spools.
