The Expanse MCRN Corvette - Rocinante

UPDATE 23th June 2020: User Freich spotted a mistake, I accidentally uploaded a wrong version of the PDC stand. Should be fixed now. I have also uploaded a new version of the stand with a deeper cutout at the back, called Roci-Stand-Addon-PDCs.stl. Depending on your method of attachment for the standalone PDCs, this one might be a better fit. I recommend testing the fit by printing only the top part of the stand (e.g. in Cura by pushing the stand 41 mm into the ground). UPDATE 7th May 2020: Added (a very WIP version of) standalone PDCs. You can now print the sleek version of the Roci and add PDCs later, should you wish. You can even rotate them around. I am currently working on standalone printable PDCs, so if you decide that your awesome Sleek Roci is not threatening enough, you don't have to print the whole thing again. Printing the Roci with PDCs already on there can also be support-intensive, printing individual PDCs is way easier and requires minimal support and cleanup. The new Roci now has 5 sections: 1. Drive (same for both versions) 2. Connection plate (same for both versions) 3. Back section (sleek and PDC version) 4. Mid section (sleek and PDC version) 5. Top section (sleek and PDC version) All parts are already oriented for optimal printing. No supports should be needed for the Drive and plate sections. The Top and Mid parts require minimal supports under the bottom vents (and even that is optional for the mid part). The back section has vents on the bottom - set up your slicer to print them as bridges (horizontal and vertical lines, not diagonal) and they will look like awesome vents when done (In Cura, you can do this by going into the Experimental settings and playing with Bridge Settings - lower the Minimum Bridge Wall Length and crank up the Bridge Skin Support Threshold - I got mine at 4 mm and 90 % and it works like a charm). PDC versions obviously require extensive supports, I had decent success with Cura's tree supports. 6 keys are needed for the full ship. The keying positions have unique offsets between parts, so the model should only go together in one way and look even remotely right. They have a 0.3 mm tolerance at full scale, you might need to experiment with different sizes depending on your printer, especially for different scales of the ship (for example I had to print them at 47% scale for my 50% scale Roci to fit comfortably). They are not made to pressfit and hold the ship together, just to aid in gluing the parts together. So far I have successfully printed a 100% scale sleek version, 3x 50% scale versions (2 with PDCs, one sleek) and a 25% scale sleek version, all of them in parts and glued them together. All at 0.2 mm layer height. The 25% scale was a bit of a PITA to put together, but it is possible. Work in Progress, all criticism welcome.
