Valkyrie GEV SF tank 6mm - 3 variants

thingiverse

I remixed these fantastic 10 mm tanks into a set of 6 mm ones. The assumption was that the original scale was 1:182.88, according to Wikipedia's list of scale model sizes. This is a bit ambiguous, but it worked fine as a starting point. I chose 1:300 as the target scale, but there are several close scales around that mark that could be called "6 mm" (again, according to Wikipedia). Close enough. The models were thus scaled to 0.6096 or 60.96%. Halfbat was kind enough to include the source Blender file for the models, making changes easy to make. There were quite some slicer warnings in the beginning, most of which could be fixed by recalculating some normals in the mesh. I combined most of the submeshes into bigger mesh groups for easier handling. I also created some vertex groups of model parts and added materials for rendering in Blender Cycles. There was a third variant of the tank in the Blender source file, which has an artillery turret on the same chassis as the other ones. I also exported that one to STL for printing. Since I never intended to print the file on an FDM printer, I totally ignored all kinds of internal geometry from overlapping submeshes and whatnot - I intended to print these models on a DLP printer, which is way more forgiving in this regard than the FDM slicers I've worked with so far. I printed one of each variant on the Anycubic Photon using Monocure Rapid Grey resin. Prints were angled 5 degrees backwards and on heavy supports in the Photon Slicer. Overall, I'm mostly happy with how the prints turned out. There's still a few kinks to iron out: * The bottom edge of the skirt is sagging a bit between where the supports were. Since these tanks are supposed to have a flat edge at the bottom anyways, I'll probably extrude the bottom skirt out a bit, so I can sand it back to a straight line after printing. * A few areas of the model are slightly skinned over from my printer. I don't exactly know why this happens (e.g. visible if you compare how the blower fans turned out, some are really crisp with each and every propeller blade visible, others are kind of filled in with excess resin and skinned over) * The pegs on the turrets were pretty much nonexistent. They were long enough to align the turrets for gluing, but not enough for loosely assembling the tank so the turret could still turn * The front chassis laser is really tiny and hard to get a grip on for sanding, maybe I'll print that one together with the chassis next time Based on simple 30x40mm bases printed on an FDM machine, base surface structure provided by printing surface. Edit: I added the STL exported from my DLP printer's slicer (Photon Slicer) with the aforementioned layout and including supports. I also added the config file I used for printing with Monocure Rapid Grey resin and the sliced Photon file ready for print.
