This square trick box has a hidden latch mechanism.

This remix of the original Twist Lock Trick Box (hexagon) uses a square base and cap.

Just like the original, this can be customized with different topper designs. Any topper created for the original will work with this version!

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.

I've tested printing the spring in PLA and PETG. So far, it has worked well, but some filament may bend and withstand regular use better than others.

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. I recommend using either super glue or 3D Gloop!, but hot glue can work as well.
