Gear Attatchment for TLRs like Rolleiflex, Rolleicord or Yashica Mat to synchronize polarization filters in front of viewing and taking lens with gears.
I used polarizing filter from a 40.5mm screw in type.
I use the "cokin" version with my Cokin A filter Holder: https://www.thingiverse.com/thing:6761447
I also designed some "stand alone" versions, with buttom or side adjustment wheel(s).
The stand alone versions are untested as a whole, BUT the "gear part" works In my cokin model and the the bayonet fit works in my filter holder.
Rollei's use basically the same bayonet, but might require a tighter fit.
Feel free to change the models to your requirements.
