thingiverse

This is a deck featuring a 12 foot diameter fuel or water tank that can be positioned atop the switch machine's slide. You can print out either a slide that fits on top of the DPST switch and underneath this deck with or without a vertical peg to attach the control wire headed towards the turnout. If you use the hole located at the front of the deck, then print the slide without the peg that is available here: https://www.thingiverse.com/thing:4279017. The deck with the fuel/water tank is slid back and forth to activate the DPST slide switch underneath it, also flipping the turnout via the control wire attached to it. The DPST switch can also reverse the polarity of the frog. More information on the switch machine and how it functions can be found here: http://1fatgmc.com/RailRoad/3D-Printer/3D-Printer-Index.html. Further details on the fuel/water tank are available at this link: http://1fatgmc.com/RailRoad/3D-Printer/page-13.html. Prints were produced with an Ender 3 Pro utilizing Cura set to 'Super Quality' in the 'Profile' setting and featuring a standard .4 nozzle.
