Sigma 100-400mm f/5-6.3 DG OS HSM - Lens Collar - Arca Swiss Mount

thingiverse

Simple lens collar for the Sigma 100-400 lens. Arca swiss plate. Designed in Fusion360. The hinge needs a 5mm rod of almost any material. I've used a piece of carbon fiber but anything with that diameter will work. Make sure it's glued only on the outer sections to allow free movement of the hinge. The bolt used to lock it down is 80mm long (a little shorter will work too). It's 4.85mm in diameter (I can't remember exactly what type/pitch/threads it is). The nut that fits in the print is 8mm. Any type of bolt/nut combination close to above measurements should work. I can't find the knurled knob design, I suggest print something like thing:439239 adapted to the bolt you are using. For strongest parts, print the sections lying on the "back" side and use supports for the split section. I am open to making any changes/additions to the design on request, just send a message.
