Yes I have spent most of 2020 (after finishing my original) developing a cheaper alternative to manufacturing this prop. Please check out page 5+ of
this thread (ZF1 build thread) to see progress on it. It's already fully animated with movement and lighting and consists of 3D printed plastic components (with aluminium frame) as opposed to hand machined metal parts and will be sold as an unassembled, unpainted kit. I'll be starting a new thread when this project reaches V1.0 and is available for sale. The price will be £500 (£750 for assembled prop and painted shell) + shipping.
