I designed a 36 foot long pipe load in n scale. It has wood base supports and load strapping. It is a .stl file, open for modifications. Easily scalable. Please no commercial use per Tinkercad rules. I printed it on my Mono2. It came out clean. I found that I had to dip the unit in isopropyl repeatedly to clear the resin from the tubes. After the resin was cleared I blew out the tubes with canned air before hardening. A bit of paint...
