@Gunther_Weygers great idea about Shapeways. I’ll do that!
V2 doesn’t have film cleaning as part of the design…yet. I did come across a couple of good and cheap ideas (which I can’t seem to find right now) how to approach this but haven’t incorporated them into the design. I am, however, leaving room in the film path for additions such as this that I hope the community will take advantage of as they build their own features.
If you find any designs you like, please add them! I found this old thread: Wetgate Solution? - #3 by tguinan
