Filter holder bracket 76mm for photo enlargers

thingiverse

This bracket makes it easier to manipulate with grading filters in photo enlargers, simply glue this bracket to your filters, and done! of course, resize if you need a different size (this size is specifically for meopta opemus IV). Important to mention: if you are using a edison bulb in your enlarger, this bracket may warp, so either try printing it out od PETG, or just use a LED :)
