Mamiya RB67 focusing screen frame line templates for 6x7 and 6x4.5 backs
thingiverse
I had a blank focusing screen for my Mamiya RB67 and I needed one with frame lines for both 6x7 and 6x4.5 cm negative sizes so I made these templates to accurately draw them. If lines are only needed for 6x7 cm then just the 4.2 mm template is used, the 12 mm one is used to mark the 4.5 cm lines for 6x4.5. I made the templates slightly narrower than the actual calculated width to accommodate the thickness of the lines. I used a black permanent (still removable with isopropyl alcohol) marker with 0.7 mm tip as that was what I had, different colors or dotted lines etc. can be used for better clarity desired.
