Simple narrow kitchen shelf to stack jars and other essentials. I created it for myself but maybe others will find it useful. 

The shelf is long, narrow, and designed to be put against the kitchen wall.

Features:

• Model Size: 230mm(Width) x 225mm(Height) x 110mm(Depth)
  Max Object's Height on the lower shelf: 205mm

• Shelf size: 225mm(Width) x 105mm(Depth)

   

• easy access with support only on the back
• model created in a way to limit bending 
  (external support and internal spine)
• The upper shelf should support 1kg with no or minimal bending. (It can support much more in terms of weight but it will start to bend somewhat.)

Optional:

• There are four spaces below for optional rubber feet/pads (~12 diameter) - not necessary but will keep shelf nicely in place.
