Designed for bresser tripods but would fit any similar model.
Any gym weight disc with an inner diameter > 28 mm but < 35 mm would fit.
Minimum stack height 25 mm since the thread does not go all along the shaft. Maximum discs stack height = 40 mm.
Hardware needed: 3 X M5 bolts (min 20 mm length) with nuts.
The author marked this model as their own original creation.
