Successfully printed the lower section of the hull for V03 design on my 3D printer earlier this week. There was some slight warping at the bottom of the part (which I expected – am looking into upgrading to a heated bed to prevent this issue) and does not cause any major problems. The part was printed in PLA, with a 0.20mm layer height and 7% rectilinear infill. The print took about eight hours to complete. Major design changes include a large cavity in the lower portion of the hull for a 6600 mAh Li-po battery. The battery pack and Arduino Mega fit inside perfectly!
Next I will try to print the top portion of the hull, however without a heated build platform I expect there to be quire a bit of warping so this may cause problems for sealing to the two pieces together.
Midway through the 8 hour print. This shows the pocket for holding the li-po battery pack.
