4-8-8-4 Big Boy Tender

thingiverse

I did it again, here is the 1/15th scale 25-C Tender to go with my 4-8-8-4 "Big Boy" Locomotive I created for Makerbot back in 2014 !! When combined with locomotive, it's over 9 feet long!!! This model took about 300 hours to design and around 700 hours to print. It consists of a whopping 315 parts (including the track). The parts were printed almost entirely on a Makerbot Rep2. The only exception was the truck frame, which I originally designed and printed as one piece on an Objet 500 Photo-polymer printer. Here are the materials used (PLA): Makerbot True Black: 12 lbs (6 kg) Hatchbox Wood: 1 lb (.5 kg) Makerbot Clear: just a small amount, less than .1lb (.05kg) The Bill of Materials and Tender Assembly EASM files are available for assembly reference. The parts are compressed in the Tender STL parts RAR file to make it easier to download.
