About this 3D model

I decided that my Prusa needed new rubber feet. Rather than buying new ones, I designed this little mold myself. Use it to cast domes from silicone. The default radius of the cavities is 10mm. Scale the model to get different sizes. 150% will give you 15mm, 200% 20mm etc. http://youtu.be/2UciDHGCZX0
