Ultimaker2 rail system (U2RS)

thingiverse

Ultimaker2 rail system (U2RS) users: please TAG any published content compatible with these rails as "U2RS." To achieve maximum flexibility, we designed a printable back plate to mount onto your UM2, enabling you to attach four rails and position your feeder(s), spool(s), or other accessories according to your experiments. For further insight into the background of this idea, refer to our thread at umforum.ultimaker.com/index.php?/topic/4393-ultimaker2-feeder-system-improvements-and-ideas/?p=61867 To make necessary adjustments to your machine minimal (no drilling), our system was designed for external use with feeder motor(s). Three key parts mount to specific components on your printer. Two mounting holes accommodate your left and right feeder motor mounts using any available M3 bolts; the remaining part fits into a pre-existing plate inside your spool holder. Be cautious of your limited workspace: Do not hesitate to warn potential users: behind the Z-stage, there is only a narrow margin. This may force you to make careful adjustments when installing the U2RS MiddleScrewPlate. Mount these parts carefully so screws will point inwards (from printer side) towards outward side and do it using bolts with thin head screws (thin enough not block view by looking under). Check mounting of this piece for clarity on safety before starting assembly. Our "starter kit" contains mount configurations compatible for the following accessories: any UM2 original spool holder, UM Roberts feeder or yours of your preferred choice as a part. These pieces hang loosely to be instantly mounted or detached via the Compact low friction spools designed using this print setup here on https://www.youmagine.com/designs/compact-low-friction-spool-holder For horizontal and vertical adjustment, attach these accessories at suitable spots for support through brackets attached by U2RS single (normal one) double and special brackets. This allows your items move in whichever manner you choose when mounting it. Our single/double attachment features supports; pliers help remove unnecessary materials and same goes with holes predrilled as per instructions so they work with desired parts and not be removed prematurely while doing so or accidentally damaged otherwise when repositioning or reinserting the pieces inside respective bracket. Backplates for connection already include mounting supports designed at appropriate intervals in between the points to maintain integrity & keep safe during assembly & operational stages - edit : as previously mentioned before -
