This is the first of a few skins for my RPi Box, I have 1963 Tardis almost finished. THIS IS A WORK IN PROGRESS.
The SCAD program and uploaded STL will create a "2005" based Dalek that stands about 6.5" (165mm) tall. As it stands now, it is a sculpture. In the coming month, I will finish the scaling changes to allow printing 2x large with interior space lof at least 70mmx70mm and 100mm tal, plus wiring space to a RPi-B+ SBC as well as multiple drives and a powered USB hub to power and connect them together.
IF you the model direction, the skirt is setup to have hemi-semi printed all in one, or via "spikes", then a pyramid in stead then print up 56 bumps and 56 coins, and glue them on yourself. This is allow multicolored skirt,
Remember to remove the supports for the neck rings, I use a small pair of needle nose to pul each support out with a light twist, then cut at the notch to remove the support rings.
All mounts are designed around #4 3/8" or 1/2" even up to 3/4". These Flat Head Philips (Sheet) Metal Screws with 82 degree V head. These help center the screw. Also on the mounts and pins, watch for fine connection threads - more supports, since I use a cold bed 3D printer, I find these help a lot, just got to clip them.
The OpenSCAD software is setup to create create both independent body parts (Dome, Neck, Shoulders, Skirt and Base) as well as joined parts like Skirt and Base. Also It creates it own support structures, depending on joins in use. You can turn these supports off if you want to use your slicer's supports.
WARNING: I use Repetier and a few of these SSTL are flagged amaked as "Not a manifold", thought OpenSCAD as well as mesgmixer do not find any errors. I believe the issue is with number and size of small objects, since this planned to scale as needed. I just clock the fix button, and Repetier software is happy.
