This is something we’re in the process of test printing right now. It’s a negative/ hollowed out double Helix, encapsulated within a cylinder which is intended to be printed in a clear resin on our SLA which must be high polished to a glass-like surface to show the double helix inside. Our first test was too small of a scale and the double helix barely showed up after the exterior of the cylinder was sanded and polished to clear, so I doubled the scale to the files which are posted on here. I’ll post pictures once we get our next successful test prints of the parts and polished up.
