I've designed a 3D printed lens hood for Zeiss ZM lenses (43mm and 46mm bayonet mounts, i.e. ZM 25/2.8, 35/2, 35/2.8 and 50/2). These are a bit more replaceable and expendable than the original Zeiss hoods 😉

M43 Version (43mm Filter Size)

The 43mm version fits the following lenses:

• Zeiss Biogon ZM 35/2
• Zeiss Biogon ZM 35/2.8
• Zeiss Planar ZM 50/2
• Zeiss Tele-Tessar ZM 85/4

M46 Version (46mm Filter Size)

The 46mm version fits the following lenses:

• Zeiss Biogon ZM 21/2.8 (untested)
• Zeiss Biogon ZM 25/2.8
• Zeiss Biogon ZM 28/2.8
