FoldaRapX
Back to the concept of a foldable reprap using a scissor-like mechanism for the Z axis :)
R&D
- Pmma-prototype.jpg
scissor movement, smooth and without play along the linear movement (thanks to press-fitting everything), but some angular play in one of the bearing (balls/cage).

press-fitting the 695zz bearings (5x13x4mm) and D5L10 spacers with a vise works (the spacer outer diameter is 5.1mm in fact)... but using D4L10 shoulder screws and 604zz bearings (4x12x4mm) instead will be easier, I will keep that in mind for the next iteration.
was imagined during the initial concept of the "FoldaRap2" mid-2012, then named "Mondrian" when it was not pursued at the time
