Step 1: Parts and Downloads
You will need to print two handles and two rails to build the rig. Print the handles at 10% infill and the rails at 50%+ infill to prevent flexing under weight.
I have also included a couple of accessories. The first is the iPad Mini grippers. The second is a cord keeper that I use for my lavalier mic.
Other required parts and tools
Allen key or screwdriver (depending on the screws you chose)
(4) 3/4 inch long screws with 1/4"-20 thread. to attach handles to rails.
Some 1/2 inch long screws to attach your accessories how many depends on what you chose to mount.
optional - I found some knobs at my local hardware store that make it easy to move and adjust the mounted accessories.
Step 2: Assembly
Insert the handles over the raised rings on the rails and attach with 3/4 inch long screws.
