HO Scale Coal Tipple

HO Scale (1:87.1) Coal Mine Tipple for Three-Track Facility Still a Work in Progress I'm currently working on an HO scale coal mine tipple for a three-track facility, and it's still very much a work in progress as I don't have all the parts meshed together yet or even designed, for that matter. The full design is intended for three tracks with 2" spacing and flat surfaces. However, I might build up the landscape behind the tracks and under the back of the structure to add some depth and visual interest. All of the parts may need to be rotated to slice properly, so I ran them in ABS with 100% infill and a very slow layer 1 to ensure good adhesion. The floors will be changing as I figure out the locations of the chutes, and I'm considering whether or not to add roofs, possibly using sheet ABS for them. Still have quite a bit of work left to do yet, but I'm having so much fun that I wanted to share it with you! I still plan to add another tipple in the back with a conveyor to it, and there are some holes to lay out yet on the one larger wall. The walls are pretty thin at 1.4mm plus some rear supports, and I'm printing at 0.2mm layer height. There is no outer wall detail as I plan to cover it in corrugated metal, which will be 'stamped' from the patterns I designed and have on my profile. UPDATE December 28 I've tweaked some of the rear structure and uploaded more files since then. I'm working on a support beam design that will print well and look decent, but it's taking longer than expected. I also need to add another tipple with a conveyor from the 'Large North Wall,' but I uploaded a version without a doorway for anyone who wants to build this beast quickly. Still working on getting a good layout for the main floor sections, so once I get that done, I'll upload beams, floors, and footers. Thanks for watching! UPDATE My 2019 I just wanted to let anyone know who might be watching this that I haven't abandoned it! Life has been hectic since Christmas, and I've just not had any free time to continue working on it – but my layout will always need a coal mine, and this one fits perfectly! I'll begin again with the freecad design and upload additional parts when time permits – maybe once summer vacation comes. Thanks for watching!
