Polymaker Cardboard Spool Adapter - PolyTerra Edition

One thing I appreciated about the Polymakers Adapter was that it kept the cardboard dust out of my AMS. The one thing I didnt like was if I wanted to remove and reuse the clips on the outer ring broke off too easily. My solution was to make posts that slide into the filament holes and then add slots to the posts to clip in the inner clip. This will also help not add unnecessary bends to the filament.

Update 2.18.24 - Change the thickness in order to have better compatibility with all PolyTerra rolls out there.

Polymaker's Description from the original spool adapter

The Polymaker spool adapter is designed to help your cardboard spools print more consistently by reducing friction and creating a structured rolling surface. The spool adapter clips around the face of the Polymaker cardboard spool and is fixed in place by three small tabs that grab the edge of the spool and a location pin that stops the adapter from spinning. The adapter can help your 3D printer by reducing the rolling friction when mounted both internally or externally on almost every design of the spool holder.

One benefit that the cardboard spool provides is durability. The spool can be dropped off a table without shattering, unlike our previous plastic spools. However, this bends or deforms the cardboard face of the spool leading it to unspool with a wobble. The spool adapter can solve this issue by providing a solid circular rolling surface to interface between the spool and spool holder.

Multi-material stations that have assisted unspooling are often designed with small intricate gears that can get jammed by dust particles after hundreds of hours of printing. The spool adapter can eliminate the problem of dust build up and allows Polymaker spools to be compatible with all multi-material stations, such as: Bambu Lab's AMS or Ultimaker's Material Station. Our spool adapter design is by no means perfect, so we encourage you to remix and redesign it to suit your needs where necessary. This design was inspired by our community so who have already designed and posted many similar rings and adapters.
