A spool holder for Mosaic printers. The system is detachable for easy transport. It reminds me on my old Super 8 projector, so I gave it that name.You need a 15mmx15mm aluminum profile. Cut it at about 45-50cm. The clamps snap easily on the Mosaic frame. I printed the parts with 50% infill and am quite happy with the result.The top part (holder) needs to be glued to the aluminum profile. I recommend to glue it with an angle (less than 90 deg) to the profile, so the spool does not drop off the holder while printing.
