Hey Alex, sent a message back. Happy to help where I can.
It seems like there are a few people on here/fb group have have been looking for an retractable dustshoe system for the Sienci ATC.
Lol I feel like at some point Sienci should just built a motorized retraction system that triggers based on M8/M9 and the community can then build custom solutions on top. A fun thought excersize of what could be.
