I am trying to cool an aspirated laboratory bottle, through its base. The bottle is 120 millimeters in diameter. I have 13 millimeter outer diameter silicone tubing that I can pump a chilled liquid through to cool the bottle.
I want to 3d print a shape that will help me shape the tubing path underneath that bottle to cool it.
I need to generate a shape I can import into Tinkercad to integrate the shape into a larger project. Tinkercad supports stl, obj, and svg files.
The base shape I need is a solid disc: -120 millimeters in diameter -15 millimeters thick.
I am going to nest the 13 outer diameter millimeter silicone tubing in a spiral channel cut into the top face of the disc.
Entrance: Remove a 13 millimeter hole through the radial center axis of the disc. This allows the tubing to be connected to the chilled liquid source.
Exit: Add U shaped channel cut with the common profile as a radial cut starting at 270 degrees moving towards the center of the disc with a length of 13 millimeters. This allows the tubing to be connected to the sink.
Spiral: Add a common profile channel cut that spirals from the entrance to the exit.
