Petzval 58mm Aperture Effect

Aperture effect inserts for 55mm Petzval lens, case and template.

Print using black filament at 100% scale, 100% infill, no supports and no brim.

Use a rubber band to retain the bokeh filters in the case.

If making your own bokeh filter, use sheetmetal 1mm x 27mm x 59mm. Mark out the round ends with the aid of the template.
