Here’s a teaser sketch of the new camera slider (click to enlarge).  The belt anchors are different from the old one, but otherwise it’s almost the same.

It’s made of a standard MakerSlide carriage plate (green) and a motor mounting bracket almost identical to the one used for the Z motors of the ORD Bot (yellow).  The buckle-like belt anchors (blue) should be easier to use and sturdier than the earlier version.
