Not willing to sell my liver to buy such a handle, just to make some videos of my son, I designed my own easy printable version.
Was made for the smallrig-cage of my Sony ZV-E10, but should work with many other smallrig cages.
Printed in PLA-CF as it is the perfect material for the task in my eyes, great strenght, and good overhang printablity.
As hardware you only need two ¼" by 12mm FHCS-Screws.
Have fun.
And sorry for the bad pictures, my camera wasn't willing to photograph itself ;)
