To assemble, take a saw and clean up the slot as well as the bridge.
Mount with 20mm M5 hex screws and M5 nuts.
Be careful to buy screws with an overall length of 20mm and not with a
20mm thread as these will be to long (as it can be seen in my pics).

Changelog:

020 : Slight fine tuning (see .scad for list)
017 : Added top and bottom phases (first version to release)
016 : Re-implemented support material
