About this 3D model
Octagonal spool roller to roll them all. Easily printed in different orientations. Remixable for different attachments. Changelog Date Description 20-04-2024 Merged different variants in this model 15-04-2024 Released v2. Increased roller skirts to prevent some spools from side-slipping. Reduced roller radius accordingly. There are multiple length variants available for different spools: 60mm Print this if you are using narrow spools that usually contain less than 1kg of filament (Fiberlogy/Prindano/Ultimaker) 70mm A common choice for a majority of 1kg spools (Creality/Elegoo/Esun/Rosa3D) 80mm For rolling thick bastards carrying a little bit more than 1kg of filament 90mm For rolling even thicker bastards 110mm For heavy 3kg spools You can choose a specific length if you are constantly (re)using the same spool, or simply choose a longer variant if you are using filaments on spools from different manufacturers. This spool roller has multiple attachment options: For 30mm threaded insert The most common thread on factory spool holders coming with Elegoo/Creality/Artillery/etc For Honeycomb Storage Wall For IKEA Skadis pegboard (coming soon) For Multiboard For your specific need (just remix the attached f3d) Parts list 2x 608 ball bearing (in this specific application cheaper → better) Printing recommendations Tune dimensional accuracy to achieve the best results You can experiment with printing orientation but printing vertically with an insert on top works all the time Use 10mm inner/outer brims to prevent corner lifting and falling Use manual tree supports only on 2 flat overhanging surfaces The roller has an embedded sacrificial layer for printing without supports Use material and settings that allow bridging Assembly Remove the brims and cut off a sacrificial layer from the roller using clippers It MAY require some amount of post-processing(sanding) depending on how clean your supports(filament) come off Slap 608 bearings on the roller Attach the assembled barrel to your printer/wall/whatever Drop the roller into the barrel Hang your spool Enjoy smooth ride P.S You can buy me a coffee if you like this model
