I wanted to make a shelf that I could print really quickly and use wood as the shelf itself. 

These sides print really fast and you can just slot in 9mm x 44mm wood strips. 

Provision is made for another piece of wood if you want to add a wood strip with holes to secure the paint bottles or anything else really. 

I designed this specifically for my vallejo paints. 

Printed with normal PLA, no supports and with a infill of 15%.
