Spool Supports for MP Maker Select 3D Printer v2 (and Prusa Mendel i3 3D Printers)
The (U/T) bracket fits over the frame to prevent sliding fore 'n aft ... it fits into a 1" PVC pipe as you can see in the printed examples ... I use the electrical PVC since it's gray and has the nice larger diameter end that fits perfectly over the printers extender arm.
The second part is to help hold the PVC pipe horizontal, but really isn't necessary.
As you can see in the printed photos I cut the flared end of the PVC pipe long enough to hold two fat spools of filament, although you can just cut it a little shorter and move the bottom PVC support closer to the spool arm.
I've also thought about making another arm sticking out on the right side to hold a couple more spools ...
Teaching young children a little bit about electronic circuits, sensors, motors etc., about structured programming, phonemes, 3D printing and art so they can learn to build their own toys and invent!
