This is a 3D reconstruction of the bacteriophage T7, solved by cryo-electron microscopy and 3D image processing. This model (which is not from my own research) is available as part of a schools project in partnership with the Society of General Microbiology.
This model was produced from a reconstruction deposited in the EM database - EMD 1164 and published:
