Summary

This bracket is for 80mm diameter outlet (hot air) hose from diesel heater.
It attaches to the edge of a ~20mm shelf.
Allows it to be routed along the edge of a shelf, with t-pieces being added where necessary to direct the air "blast".

It does not work with PLA. Its a very hot heater hose.
The heat softens the material and the weight of the hose allows it to bend out of shape.
Not tried ABS or any other material as yet.
If any success with other materials let us know.
