Curiosity remix for easier print

cults3d

This remix makes it possible to print the rover model with a small printer and it adjusts for some problems in the original NASA model that makes it very hard to print. The remix also adds the option of printing different parts with different colors, since the parts are now separated. I used my own software to separate the original NASA model into its individual disconnected parts, and got 24 parts if you include the supports and some tiny pieces that didn't seem to be significant. In this remix, duplicate wheels are omitted, but see the discussion below on printing the wheels) Another reason for separating the parts is to be able to print them in different colors. A third reason is to reduce the risk of complete ruin of everything if one piece fails. I found that the underside of the main rover body was originally designed with a thin rectangular void on the underside, which essentially made it unprintable. So I filled it in and it was then possible to print without problems. This modification is not visible in the finished model. I also increased the height of the supports where the wheel assembly connects. The support still breaks off easily. The wheels were a problem, because they were designed with very small footprints, and thus very likely to fail during print by losing adherence. After 3 unsuccessful print attempts, I modified the wheel spokes to extend all the way down to the print bed in order to increase the footprint and adherence. Now the print of the modified wheel was successful on first try. This modification is on the inside of the wheels and not visible in the assembled rover model. Both the original and the modified "easy" wheels are included in this remix, I recommend to print the easy one. Print 6 wheels together at once by instructing the slicer to slice multiple copies of the one you prefer. The small UHF part is not from NASA, it is my own tiny bonus contribution to make the UHF antenna stand out like in some of the pictures of the rover. I printed the model using 0.2mm layers and 0.2mm extrusion width.
