Where is it described?
The tabernacle lamp stand is described in detail in Exodus 25: 31-36
Has a center stem with 4 cups and knobs, and 6 branches with 3 cups and knobs.
The cups are shaped as the almond bloom.
So here is my interpretation.
Not perfect by all means. but a nice project to do in Blender.
