Spool Roller

Update 3/23:*Per a user request I've added a large version of the spool roller to accommodate 3kg spools (270mm dia x 104mm wide).

Update 12/13:Added a self-centering roller. The new roller has a concave profile that should keep the spool centered on the rollers. Although the standard rollers are working just fine, I decided to try to step up the design a little.

This is yet another spool roller. I am currently printing with Ultrafuse 316L Metal Filament. A spool weighs 3 Kilograms. I tried printing using my standard spool holder. But, the heavy spool applies too much weight on the holder. The excess friction causes extrusion issues. I looked on Thingiverse for a spool holder, but found they required parts that I didn't already have kicking around; ergo, I designed my own.

Parts required to complete:

• 4 M6 x 16mm screws
• 4 626 Bearings

Notes:

Print as oriented in stl's.

To get the best surface finish on the rollers set the following:

• Outer Wall Speed slower than normal. I set at 20 mm/sec.
• Z Seam Alignment to user specified. Set so that the Z seam is lined up and not random. This will allow easy removal of the seam if necessary.

Post-Printing

The rollers have a built-in support structure on one end which can be removed easily with an X-acto knife.

The base's screw holes have a light threading that will aid in starting and aligning the screws. The screw cuts part of the thread itself. Prior to final assembly screw in the screws to cut the threads and then clean off any plastic bits.

Insert the bearings into the rollers and then tighten the base screws so that they pass through the washer and into the bearing.
