Roadbook box

I made this box to mount roadbooks up to 15 cm wide.

The only materials you need to build it are the following:

- 8mm threaded rod: 2 units 235mm long
- 8mm aluminium rod: 2 units 180mm long (optional, you can use the same threaded rod as before)
- 8mm nuts: 16 units
- Ball bearings 8 x 22 x 7mm: 4 units
- Transparent methacrylate sheet 130 x 180mm
- Rubber bands

The assemblage is pretty simple and the pictures are self explanatory.

I attached the freecad files so you can make your own adjustments.
