The file 'HVAC SUPPORTS ALL SCALES 3D Printer Model' is (stl) file type, size is 22.5KB.
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.
I exclusively print with PLA and have found that ordinary clear lacquer thinner (Nail polish remover) is a wonderful glue. Make a small test for yourself of two pieces of scrap PLA and give it a try. Let sit for 20 seconds and then try to break it apart. It leaves no residue and is applied with a small brush. I've been using lacquer thinner as a glue on styrene and PLA for years. No sloppy or messy glue to show when finished.
Here's an interesting point for me to bring to your attention. Every model that I have designed is based on real world measurements and therefore each building is interchangeable with other structures. Simply bring the .stl file into any CAD program, even the wonderful TinkerCAD and combine to make a completely new design to 3D print.
If you would like me to design a custom model for you contact me directly at:
It is totally free but I will post it on Thingiverse for others to print and enjoy.
Happy modeling,
