Printing

This model can be printed entirely without supports!

The spring should be printed with enough perimeters so that the thin arms of the spring are made entirely out of perimeter lines. This will make sure it bends in the correct way.

Base.stl and its various sizes has 15mm long bridges. These need to be printed straight or the latches won't slide as easily into place.

Assembly

Assembly is the same as the original Twist Lock Trick Box. Watch this video for the complete process.

Make sure to pre-tension the spring by one gear tooth. This will assure that the latches have a strong hold on the base. This is also necessary for the alignment of some toppers.

Make sure to glue the spring and topper If you do not fully secure these parts, the mechanism may become detached while in a locked state.
