Thanks for the reply @erik
Since the lens requires making a custom faceplate for the front of the chassis anyway, I would figure if it's made such that it's positioned with sufficient clearance for those components it would work, or is cable length a scarcity? there's screwholes on the M12 mount that I could use to secure it stably to the front faceplate (note, does the connection in this case use the FFC connector on the shop's FFC board or the brown/black port on the front coming from the sensor directly? from that render it would seem the latter)
Since I'd be remixing the front half of the case, I don't mind it being a bit bulkier to fit the mounts and everything, just that it would be possible to do so and that with clearances and sitting straight the cables still make it.
Also, do you have a STEP file or similar available for the M12 mount part? I wasn't able to find it on the github documentation
