![]() ![]() I found that 0.2mm worked well in the slicer and produced a decent result. The bump on the front and rear can be virtually eliminated with good filament and some good print settings. There is the large gap in the sides that has to be bridged, but I really had no big issues with pretty standard settings, other than the bump. The body was printed in the vertical position, with no supports. The print orientation should be pretty evident. These were printed on a Prusa Mk2, using PLA for all parts. Not true to original, but it's at the back, and allows one to use a straight mini-USB connector straight up. Portal turret v4.zip is updated and should contain all printed parts needed to build the latest turret. This made manipulating and keeping sub-assemblies linked for quick access. I learned quite a bit on this project, such as using embedded components within other components. This was pretty taxing, as there really aren't many boxy shapes in this thing, and it closes up pretty tightly, with no real access for tweaking once put together. This model is what came of those changes. Once that worked out, I went back to the model and made some tweaks to improve appearance and assemblability (is that a word?). Once the entire model was built and I was confident that it would work, and could be built (printed) and assembled, I went ahead and printed out the parts and built a prototype. Why? Because I wanted to use a crank mechanism, that's why! This added some complications, but it also had a benefit once the geometry was determined, operational repeatability would be ensured and the min and max limits were pretty much guaranteed. The wing opening mechanism was a crank and slide mechanism.
