Repkord Snap Roller & MagTrack System

NOTES ON SNAP ROLLER SYSTEM Inspired by the original TUSH design, we saw an opportunity to push the limits even further. We took what was great and made it better - stronger, more reliable, and featuring a magnetic option for easier setup. Standard 608 "Skate" bearings provide smooth operation and are widely available. The snap roller system was initially designed for the Repkord RepBox, but we decided to make it universally compatible. To ensure seamless integration, we've included connectors for use with any printer model. You'll find a range of rollers and tracks to suit different setups and magnet sizes. Whether you're looking for a single or double configuration, our system has got you covered. PRINTING Before printing, make sure your printer is well-tuned and calibrated. Tolerances on this model are tight, so it's essential to use a printer that excels in dimensional accuracy. We've had excellent results with the Prusa MK3 and Creality CR-10. SLICING: Print at 0.2mm layer height or finer with 100% infill, using two top, bottom, and shells. A 0.4mm nozzle is highly recommended. MAGNETS For optimal performance, we recommend using 10mm x 3mm rare earth neodymium magnets in a double configuration. When installing the magnets, ensure that you alternate polarities on either end of the roller to achieve proper click-together functionality. DOUBLE ROLLER In addition to single rollers, there's also a double roller model available for maximum compactness and space efficiency. You can also achieve this by clicking two singles side by side at a minimal width cost. BEARINGS Standard 608 "Skate" bearings provide smooth operation and are widely available. ASSEMBLY Due to the metal bearings and strong magnets, it's easiest to snap together one end at a time. Once you've secured the magnet and bearing on one side, check the polarity of the magnet with the second magnet. Then flip that second magnet and snap it into place along with the second bearing. Remember to alternate magnetic polarities at either end of the roller. TRACK The track is designed for maximum versatility. You can extend your system by using the double connector to snap pieces together through dovetail joints. Before placing magnets, lay out your spools next to the track facing up and press in magnets at each spot where a flange lines up with a magnet space. If you're clicking two snap rollers together, only place magnets for one side, leave space for the adjoining roller, and repeat the process until configured to your liking.
