Notes :
- tensioning the z-belt should be done in the upward direction, in order to tension against gravity

To-Do
Version 0.2
- change the aluminium flight case (not cheap) for a regular wooden flight case (easier to use and customize)
- move the linear rail 5mm closer to the pivot, in order for the end rail (printed part) to play its role of mechanical stop
Version 0.1
- fine tune E step value (837 for start)
- test print
- tweaking RepRap Firmware for the scissor Z... (will need help here)
R&D
once assembled there is more rigidity than what I feared to have, thanks to alternating the orientation of the scissors (good intuition here) the material works mostly in its horizontal plane, so even plastics seems fine (except that a scissor broke for pushing to far) - [video of a test move]
was imagined during the initial concept of the "FoldaRap2" mid-2012, then named "Mondrian" when it was not pursued at the time
