Tabletop Wargame Terrain: Refinery

thingiverse

This is a kit of parts to build all or some of the Warhammer 40k scale model pictured. Although it can be printed with a 0.4mm nozzle, all the parts (EXCEPT the valve wheels and their mounts) were designed to be printed quickly using a 0.8mm nozzle at 0.5mm line height and 1mm line width, although the walkways, ladders, X-girders, and handrails were printed at 0.25mm line height, The tiny valve wheels and mounts will need a 0.4mm nozzle at 0.2mm line height and 0.5mm line width, and probably a brim (3 to 5 mm). The rivet strips will likely foul your extruder if you print more than one at once. Multiple retractions while printing only a tiny amount will wear out the filament between the extruder's cogs and it could just stop extruding half way along a 2nd strip, although it might be worth trying 2 or 3 in a "one at a time" mode attempt. The cylinders should be re-sized to the height you want in your slicer. I made mine 50mm and 100mm for the short/long tanks. The pipework seen here is made from DIY crazy-straw kits, and this model needed about 2 and a half kits. Any amount of piping going anywhere will do. The base is any rigid flat sheet you want. The CAD files included are the parts, use this if you want to produce edited STL files, and a file with the parts assembled. Don't use this for STLs because the final tweaked parts may not be in it. The valve wheels and their little mounts are designed to fit the silicone joints in the crazy-straw kits I bought, which had a 6mm internal diameter. The 4 round holes in the walkways align with the holes in the T-girders, which assemble with the flat side down so they look like I-beams when together. The slightly taller T-girders (5mm6T) are for the horizontal tank walkway. They raise the height a little so the walkway clears the tank, and can use the same stairs to connect to the middle walkway. The difference in height is not essential, I just wanted the walkway a little more spaced from the horizontal tank it's on top of. Thinner T-girders (5mmT) support the other 2 walkways on top of the 6 tanks. Best way to assemble is to join the walkways to the vertical tanks first, then site them on top of the square X-girder assemblies. The holes in walkways and tank-tops will be visible, but will need drilling out to the size of whatever you use to dowel them together. I used 2mm plastic rod for this. The shortest handrail end sections don't have their own stl file. They are just the "REFINERY-handrail.stl" reprinted twice, and cut into suitable lengths.
