I recently had to print some connection tubes for 0.5x0.625 inch pvc pipes. I needed these in order to model a thermal convection loop which we could use for a clear model that shows the mechanism behind the TCL in my research lab. The real loop is used to model liquid salt flow through a reactor. Using dye we can show the process of convection in the clear loop we will build using these parts. The parts were quick and easy to print at the design lab.
