Uses standard M8x10mm screws as counterweights, I used the low profile variant that weighs in at around 7 grams each for a variable weight of 49 grams.
The prints, two threaded M5 inserts, and two M5x25mm screws add another 31 grams for a total weight of 80 grams.
I've dimensioned the holes for the clamping screws to work with most M5 heat-set inserts, like the ones from 3DVerkstan, Ruthex, or CNC Kitchen. The maximum length of the insert is around 10mm.
The holes for the M8 screws are printed directly into the model and are intentionally sized so they should not need to be forced in.
I used a 3D Scan of the DJI RSC2 that I did with my Einstar 3D Scanner as a base for modeling and checking for interference, you can see some of it in the pictures.
The author marked this model as their own original creation.
