On another thread Gunrunner John asked to have an HVAC unit printed to match the ones found on the Rocket Train. SEE thread. Rocket Booster Train A/C Units | O Gauge Railroading On Line Forum (ogaugerr.com)
I designed the AC unit but it has 4 tubes coming of the unit's rear going into the rocket storage car.
since the HVAC unit sits on a separate support and truck base, see above. from the rocket car; the hose between the two must be flexible.
Using FormLabs 3+ printer and FormLabs flexible 50A resin I designed and printed the end hose/tubing
and printed it.
These resin prints are printed as flexible tubes so that as the rocket moves thru a curve it flexes.
Also, I combined the four tubes into one print as shown but I think this is too stiff.
The would also have to have an attachment plate to attach like the prototype I would think.
