This is a set of brackets to add an arri anti-twist mounting point to a plate using 1/4"-20 screws. It can be used as an extension as well. It may seem silly to use three screws instead of one to mount something but believe me it's worth it ! You have the peace of mind that your monitor, transmitter or whatever your using won't literally turn your back on you :)
The .step files are also provided :) I would have loved to make it parametric for everyone but I do not have a paid version of fusion 360.
I published 60, 70 and 80 mm versions for both threads as well as a single arm version that fits the Arri 1/4" pattern spacing.
Min/max screw spacings and other lengths :
60 mm | 70 mm | 80 mm | Single Arm | Center Height/Outer Diameter | |||
|---|---|---|---|---|---|---|---|
min | max | min | max | min | max | max | |
34 mm | 47 mm | 34 mm | 57 mm | 34 mm | 67 mm | 25,4 mm | 9/21mm |
I printed it in PCTG but a version in PA-CF would make more sense if you have this.
A version with threaded inserts is available here :
