Although completely satisfied with the journal I created. My son soon suggested that I should make the doors open individually. As a book this would be very difficult and complicated to do, so I created a box.

I have reworked my original design. The handles in the original proved to be too thin and broke when I tried to insert the wood beam. I have since improved this, but have not yet printed the new design.

As with the original you will need to use supports for the handles.

Some assembly is required. the door frame needs to be glued to the box and the doors slotted into place.

to finish off, i grabbed a pic of the internet to stick in the bottom of the box.

Have now been able to re-print thetdoors with the redesigned handles and can now confirm that the beam fits perfectly.
