I’m working on a tripod mount ring for big Canon lenses. A photojournalist friend’s renting a 70-300 f/2.8 stabilized lens to cover an event soon and lamented that it didn’t come with a mount ring for a monopod. I figured I’d take a shot at modelling a simple one.
The pictured lens is the non-stabilized 70-200 f/4; gotta field test the design. Prototype is printed in regular PLA, but the final version will be temperature-resistant enhanced PLA or maybe PETT. The design is parametric, so it can be resized to fit different lenses.
The tripod foot uses a 1/4-20 T-nut heat-sunk into the plastic. The clamp uses a 1/4-20 x 1.5" hex bolt. The clamp knob was generated with wstein’s Ultimate Nut Knob Generator; it houses a long coupler nut because I didn’t have a regular 1/4" nut on hand.
