<p>You'll need two rollers, a left and right arm, and four standard 608 bearings. I recommend printing in PETG so they flex a little, making them easier to snap onto the frame. Squeezing the two longer sides of the arm together makes getting that little hump under the frame more manageable. None of it needs support except for the roller. There's a ring on the inside where the bearing goes that'll need it, otherwise the rest can be bridged.</p>
