To have the printer more compact and faster ready to travel when, only using the single spoolholder i created this adaptor.

when finished with printing move your printhead to the lower right corner.

Then you just have to pull the adaptor off the original mount, flip it by 180° and install it this way again.

In this position the Spool can stay installed to the printer and does consume less space when traveling around.

Print for example with PLA to have a strong and less flexible part.

3 Perimeter and +30% Infill recommended.
