Spool Roller

Spool roller. Designed to be attached to the top of a printer frame. Printed as multiple parts then assembled.

The rollers had a couple of issues so I might re-do them - they weren't quite as round as I would have liked and some minor raised points coupled with the smooth surface meant they didn't roll particularly well. For now I've solved the problem by wrapping them in insulating tape to create a bit of purchase and this seems to work quite well.

The bearings were purchased separately from Amazon -- https://www.amazon.co.uk/dp/B07FDTLWNF?psc=1&ref=ppx_yo2ov_dt_b_product_details
