Z-axis is progressing, models are finalizing, parts are printing et cetera.

In the meantime, X and Y endstops holders. There are two varieties to choose from, both clip on the rack. Choice is yours.
Top of rail, good if you want to have some flexibility in choosing the endstop position. Using one on my first Dollo:

End of rack. To adjust endstop position, whole rack needs to move:
- https://github.com/spegelius/Dollo/b...op_rackend.stl

Print settings:
- material: PLA or other.
- 2x perimeters
- 10% infill
- perimeter first
- no supports

Assembly is easy, just slide the switch in the slot and slide the whole thing either on the dovetails on the end of the rack or on top of the rack.
