Secret Box - Centrifugal Opening 3D Print Files

A great box to keep your small items in that's safe from those who don't know how it opens. There are no latches, catches, buttons, or switches to open this box. No matter how hard someone tries the box will not open unless they know the key. In this case, the Key is Centrifical Force. Simply give the box a spin and then pull the lid up and you're good to go.

Developed this at home to stop my kids from taking stuff like USB drives, batteries or Money from my study. It frustrates them no end that they can't get into this.

3 Components:
-Container
-Lid
-Screw Pins
(You'll also need 4 x M6 Zinc bolts)

Container size:
-Internal = 70mm Wide x 70mm Long x 67mm High
-External = 82mm Wide x 82mm Long x 98mm High

HOW TO: 
1.) Print the Screw Pins first and make sure you've got 4 x M6 Zinc Bolts ready.
2.) In your slicer set a Print Pause at layer height 82.28. Once you've reached this layer insert the Bolts and screw them in now. You can do it later but the bolts may fall over by the end and while you can pick them up through the pinhole it's much easier this way.
3.) Print the lid.

Print Settings:

4 bottom solid layers

Brim if you'd like to however if you do this with the screw pins make sure to round the edge of the pin so it inserts nicely (take off the brim on this edge that is).
