This was my first design attempt. I used google Sketchup Basic to make this. A must for any die hard Star Wars fan. base size is 100mm x 100mm easy to scale to whatever you have. The first Version I did from memory and less detailed. The v2 version is closer to the original although there are some issues with the bottom edges not right and over all needs the rounded border...But like I said my first attempt at designing anything for 3D printing. 6-22-15 I just added a hollowed version that is a hollowed open bottom version... I plan on making it clear and placing a red LED for a sith holocron lamp. It is untested as of now might print in a few weeks. Not sure if it is OK or notIts pretty much straight up print however my design does take a while and you might want to lessen the infill to take up less material and speed up the time.
