I have put together a small selection of rod holders for fishing here. The shapes are inspired by some I have found on the internet or use myself. The holder is currently designed for a 10 mm aluminium tube. A version for a heat insert is in the works. This way it can be easily removed for transport or simply swapped for other rods. Good luck!
I recommend printing the model in ABS!
