The complete design consists of the front part, one or more identical center parts and a base board.
Front and center parts may be scaled as required. The original size of the svgs and two center parts glued together fit well for my 5 meter long/ 12 mm diameter compressed air hose.
The base plate has a groove on the rear side to accomodate the supply hose from the compressor and is simply cut with the table saw. I should have made this with the SO as well...
Happy shaping!
