Like everyone else here, i got excited when i saw the model for my 23mm F2 with the window but was disappointed to see that the model got removed or canceled. When i printed it i noticed that the turning was really tight due to the mounting bar being too thick. So.. i carved out the viewfinder hole and i reduced the mounting bar by 0.2mm. It now fits snugly and it looks great on my Xpro 2. Keep in mind, the carved out area does not have a lot of stability due to lack of material so be mindful of where you put your hand when you twist it onto the lens.
The author remixed this model.
Remixed the mounting bayonet to fit less snug and “carved” out the viewfinder hole.
