Tubes

thingiverse

Just some drawings of tubular objects to string together for this and that. At full scale they are 25mm i.d. with a 5mm wall thickness. Replicas can be had at a hardware store for much less effort. I'm using these to sketch 'rough plumbing' in the lab. Eventually I plan to assemble a 'wind tunnel' for boat propellers so there will need to be some transparent sections as well but that's for another time.
