A side mount spool holder was on my “to design” list, but I had not started it yet. The back spool location is inconvenient for my set up. I have been use a spool holder on my desk that works well; only thing is it takes up desk space. I really want a holder that used the existing mount point and brought the spool to the side. The hanging holders did not appeal to me.

I saw the side spool holder and it suited my needs, but I did not have a thread insert for the bracket. So, I remixed the bracket with a smaller/deeper hole that a M4 bolt could thread in directly.

I printed mine in PETG and is holding well. I recommend using PETG or ABS/ASA.

The spool portion can be obtained from the original model files by ktothestank.
