Shoulder Rig_Part 2, Extension Arm & Handle (with Rosette)
Description
This is a video on how to use a 3D printer to create a universal extension arm and handle for a shoulder rig through 3D modeling and printing. (Use the link at the bottom below to download files shared for free) These shoulder rig extension arms and handles are designed to be compatible with other accessories with Arri Rosette connections. (The applied rosette diameter is 32mm or 31.8mm) For the shoulder rig base plate, refer to the video and file from the previous episode 01. The rosette connection method is very sturdy and can rotate 360 degrees, but there is a limitation that it can only be adjusted in one axis direction from one joint. Therefore, in order to adjust the angle more freely, it has to be in the form of two orthogonal joints, but inevitably the constituent parts increase and the structure becomes complex. Therefore, it is designed in two types, one that can rotate only in one axis and one that can rotate in both axes. (A biaxially rotating type connecting part that can be mounted on the base-plate of episode 01 has been added "Base-plate Body2") Made with 3D printed output, this shoulder rig base has an advantage of light weight, but lacks strength in terms of physical properties of 3D printing materials. (The maximum weight depends on the material of the printout or the internal charging speed, but be careful when using it with camera equipment that is too heavy for safety.) It is recommended to use metal products for screws and some parts. Parts needed -Rosette connector -M3 x5mm screws (Rosette connector x 4 pcs.) -M4 x 10mm screws -M6 x 20mm screws (Adjustable Handle Locking Screws) The handle with the remote controller is the same as applied in the previous top handle video, so please refer to the link below. https://youtu.be/qOKpkglS8zA There is no significant difference in structure from other shoulder rig extension handles that are already sold in metal, so I am skeptical whether it is necessary to design and print it. It took a lot of time and effort to design, 3D modeling, print, and assemble, but I am disappointed that it doesn't show much advantage compared to the ready-made products. (Because the printing and production process is very tedious and laborious, it may seem better to buy and use an existing off-the-shelf.) To compensate for the shortcomings of the rosette connection method, I will cover the fusion-type expansion arm and handle that combines the rosette connection method and the spherical joint in Episode 03.
