These are simple paint supports.
Three versions, with different rounding. On wood boards, depending on the weight of the piece you paint, the pointier ones may leave a mark, hence the more rounded ones. I recommend the 3mm rounded ones.
They can be used on any orientation.
Very easy and quick print, 10mn or less each, 2h30 to print 24 supports.
The author marked this model as their own original creation.
