A simple tube or pipe holder that attaches to left side of 30mm fan on the G2S Pro spider.
Tube holder is sized to hold 1/4" (roughly 6.4mm) copper tubing. Simply bend the copper tubing (best done when tube is full of salt to avoid pitching) so it points at the nozzle tip. Squeeze the end of the copper tubing, and make sure it points just below the nozzle. Adjust the copper tubing up or down so it does not touch the bed, and is about 1-2mm above the height of the nozzle. I used 1/4" latex tubing to connect to the aquarium pump.
I printed with the short flat side (with the bolt holes) down to minimize the amount of support needed. With good layer cooling, you might not need support.
Layer Cooling in action!
