Summary

Could not resist to buy some awesome Battat take-apart toys and also created some custom versions: https://cults3d.com/en/users/edge/creations.

Since the plastic threads used, is about 3/4th of rotation, it's a little delicate. That's why the provided screw machine is relative weak. So there should be a torque limited screw driver applied together with the nice collection of AndrewBougie magnet-remixe-bits, or just use this screw driver with the original bits.

The screw driver is torque limited:

  • spring loaded (pre tension could be tuned)
  • could add up to 6x steel balls (3 seems enough)
  • torque limit is (almost) independent on how hard the toddler will press the driver into the bolt
  • by design, maximum tightening torque is a bit lower the loosening torque
  • only 3 printed parts are needed, when using the standard Battat bits (choose option A)
  • or use the nice bits from AndrewBougie / remixed magnetic version (choose option B)

Use these Battat compatible bolt & nuts for replacement parts and watch some picture of alternative designs.
