Mamiya RZ67 PhaseOne H20 Mask

thingiverse

Here is a viewfinder mask for the Mamiya RZ67. You can attach some thin double-sided tape and stick it securely onto the top of the glass. Note: When using the Waist Level Viewfinder outdoors on a sunny day, always be sure to retract the magnifier carefully to avoid any potential issues. If direct sunlight hits the plastic, it may cause damage. If you don't need this print size, feel free to create one and upload a photo so others can see how it looks.
