...so now I need to make a spool holder.
Version 1
I found this design on Thingiverse:I found cheap roller-door rollers with bearings at Bunnings for $5.14 each. I wanted real bearings, rather than 3D printing a solution. You don't want filament feeding problems.
Printed a copy:
Problems:
- Side walls too thin. cracked on a slight flex.
- Had some warping from uneven cooling.
- My roller wheels were 1mm to wide (oops).
Researching warping, best preventative strategies are:
- Avoid cold draughts.
- Clean all surfaces with Isopropyl Alcohol to remove grease. It also makes the blue painter's tape super-adhesive to the plastic.
- Can slice up the object using skirt and brim settings to attach the skirt to the object.
Version 2
Decided to make my own. Removed most of the vertical wall material, and made the vertical walls much thicker. I had some perfect sized M5 bolts. I printed some bushings because The bearing diameter is 6mm, and this way I can tighten up the nut onto the bushing and not the bearing.Download and 3D View Here: Spool-Holder
Print number two resulted in a fail half way through.
Investigation found my first 3D printer jam. If only I had some device to help feed the filament in smoothly... I also adjusted the extruder spring tension off a little bit in case there was too much force applied.
Print number 3 finally working and assembled.
