Babybay Hooks

This remix adapts the original Babybay Haken Maxi for a shorter distance between the bed frame and the Babybay rods, using M5 × 40 mm socket-head screws and standard M5 hex nuts.

Changes from the original

• Hook length reduced from 227 mm to 167 mm.

• 60 mm from the outer end face of the hook to the nearest side of the first nominal 20 mm rod.

• Revised screw passages and recessed head seats for M5 socket-head screws.

• Hexagonal pockets for standard M5 nuts.

• Reinforced first rod recess: the adjacent cutout has been shortened to preserve the complete curved recess, leaving at least 8 mm of material between the cutout and the rod recess envelope.

The original 20 mm rod diameter and 80 mm centre-to-centre spacing are retained. Check these dimensions against your own bed before printing.

Parts to print

• 1 × left hook 

• 1 × right hook

• 2 × clamp

The same clamp fits both sides.

Hardware

For the complete pair:

• 2 × M5 × 40 mm socket-head cap screws

• 2 × standard M5 hex nuts, not self-locking

The screw-head recesses are designed around a nominal 8.5 mm head diameter and 5 mm head height. Washers are not included in the designed screw-length allowance.

Printing

The STL files are already oriented with their broad outer faces toward the build plate.

Suggested starting settings for a fit-test print:

• Material: PETG

• Layer height: 0.20 mm

• Perimeters: 5–6

• Infill: 40–50%

• Top/bottom layers: at least 5

Inspect the slicer preview around the downward-facing screw-head and nut pockets. Add local supports where needed and remove them completely before assembly.

These settings are a starting point, not a tested load specification.

Assembly

1. Check that the printed recesses fit your rods and bed frame.

2. Insert a standard M5 nut into each clamp’s hexagonal pocket.

3. Position the appropriate left or right hook and its clamp around the rods.

4. Insert the M5 × 40 mm screw through the recessed side of the hook and thread it into the nut.

5. Tighten gradually, checking that both rod recesses seat properly. Do not overtighten or deform the printed parts.

Testing status

The CAD models and exported meshes have been checked for valid, closed geometry. Nominal screw clearance has also been checked.

This remix has not been load-tested or validated as a safe bedside-crib fastening system. A correct dimensional fit alone does not establish safe retention.
