Easily one of most if not the most interesting gadget in this thread. Thanks for posting.
Thanks! You might be interested to know that the gizmo that holds the strip of film is actually built (in part) from a 120 film canister:

This construction is quite convenient as it provides a way to hold and store the strip in complete darkness prior to developing, and just slips onto the bottom of the rod when ready. You can even use the canister(s) directly for processing further steps, which is nice for keeping the chemistry volume low.
The biggest challenge with all of this was the film's tendency to curl or else get too bendy when trying to force it straight. The solution I came up with here simply accommodates the natural curl of the film rather than fighting it, with the strip sitting up against the rubber disk bolted to the canister lid, and then being secured with a rubber band.
