This profile is a complete CAD remodeling (not slicer scaling) of the mechanism to better fit on small hands and to withstand rough handling. The following QoL improvements are included:

Claw
- some collision points are removed from the claw model and the tip is blunt(er) to make it safer for kids.
- two claw segments now contain holes that can be used to better align and glue together the two parts using included pins / dowels.
Mechanism
- the mechanism comes in two variants:
  - mid size (14 and 18 mm inner diameter of finger “sleeves”),
  - small size (13 and 16 mm inner diameter of finger “sleeves”).
- all parts of the mechanism are made thicker and more robust to not break as easily.
- the mounting plate dimensions are adjusted so the claw is better supported and the plate does not extend beyond the claws edge.
Fasteners
- improved and better calibrated fasteners come in two sizes:
  - thinner (used by default on plate 1 and 2),
  - snug (use this variant if the default fasteners are too loose).
- the “cap” was changed to a ring that clips snug on top of the pin.
- small drop of glue can be used to make the connection permanent while the ring holds everything in place while the glue dries.

Updates:

Version 2 (25/11/22)
- Added small chamfer under big sleeve overhangs
- Enable supports so small sleeve prints without visual defects
