I designed this simple spoolholder for the few spools that wont fit the AMS lite. (It can be used without an AMS of course)
The spool carrier can be mounted on the left or on the right side, no need for extra parts.
You will need a M4x16 screw and a nut or a threaded insert.

The spoolholder itself is mounted to the skadis board with the t-clip system you can find here:

Im currently working on a tool to reach the clips better, but for now you can use pliers.

The whole thing can be printed without supports.
