Mount your child Baby Einstein Sea Dreams using velcro instead of their weird mount. I personally use it to mount on the headrest facing my daughter car seat.
BOM:
4x M2 heat insert (≤ 10mm in length)
4x M2 bolt (socket cap and ≤ 10mm in length)
Velcro that is ≤ 40mm in width
Instructions:
Print flat on the bed using heat resistant filament (eg: PETG or ABS)
Put the heat insert in the base part
Make a cross with long enough velcro and put in in the center of the base
