Give some more storage space to your Kona Electric!

Parts you need are:

1 set of 3D Printed Posts: https://www.thingiverse.com/thing:406...
Two bars of aluminium or steel, 348 and 300mm long. I used 25mm angle aluminium, 1.6mm thick. But 2mm bar would be fine, or use 3mm bar if you can adjust the holes in the 3D printed posts to suit.
Plastic tub was "Handy Crate" from Bunnings, 652 x 413 x 163mm.

Drill holes and use screws, I used short self-drilling screws that I had on hand.
