HVAC SUPPORTS ALL SCALES
Description
These simple and easy to print HVAC supports in both square and round can serve many projects and can be scaled to any proportion you need and any model railroad scale. For the ductwork use Craft Dowels in square or round, Plastruct or Evergreen shapes, simple plastic straws etc. (The plastic straws that have the ability to bend are great for the rounded corner models) Simply adjust the percent of X and Y to the desired dimension, scale them both equally if you want to maintain it as square or as a round support. Most of the time Z is not adjusted.
