thingiverse
Thanks CAD_dude for his great design, This is a simple remixed from Chinese website https://www.bilibili.com/video/BV1nS4y1d7Cw?from=search&seid=9583744878491983777&spm_id_from=333.337.0.0 Just for my 0.5 kg spool. Spool hole should be small than 60mm (depth) x 69mm (diameter) Be careful of sharp edges when turning the both side holder. There are also other good spool insert in thingivers, https://www.thingiverse.com/thing:735213/comments https://www.thingiverse.com/thing:4994736 https://www.thingiverse.com/thing:5023891 but I didn’t try.
