Spool holder for solder. I spend a fair amount of time soldering, as it's part of my job. and I'd seen others on here, but nothing that would fit the centre of my Solder spool. So I knocked this up in about 45 mins plus about another 10 for tweaks, the first version failed miserably..
Will fit a 62mm wide spool with about a mm of play, the bar clips in to the holder and doesn't move unless you give it a tug,
Modified to add a logo and endcaps. No 3D Printer? No problem. You can buy one from https://www.sledz-uk.co.uk/shop/sledz-uk-solder-spooler/
Version in picture is printed in some random Chinese PLA that I have in stock
