Print Settings & Requirements

• 300g Clear PETG
• 0.24 layer height
• 0.8mm Nozzle for fastest print times
• Dialed-in seams and print line widths (Very necessary!!)
• Some small bridging necessary
• Minimize stringing as much as possible
• Pretty easy to print if your machine is dialed in properly for PETG. This is a large print so make sure all your settings are dialed in first!

Instructions

• Print the model
• Remove any stringing
• Before attaching the return line tubing, apply some sort of aquarium safe sealant around the part's nozzle and also on the inside of the tubing (see photos, I used clear Plasti Dip). This will prevent any leaks coming through the layer lines of the print.
• Once that has dried, test run the waterfall outdoors for at least a few days to make sure it doesn't leak
• If it is still leaking, you can apply Plasti Dip to the whole backside of the print with the hose still attached to fill in any holes.
• You can paint the whole exterior of the waterfall with black Plasti Dip to prevent algae build up inside of the diffuser. If you chose to do so, mask off the ridges of the waterfall first because the 3D printed layer lines are good surface area for beneficial bacteria and algae to grow on.

Read Before Printing

• Only clear PETG is known to be completely aquarium safe. Dyed PETG may leech dye into your water over time.
• Make sure your PETG settings are dialed in and that your wall line widths are melting together seamlessly throughout the entire print.
• I have been running about 150gph through this print for 2 months now with no leaks. Just make sure the hose is attached and sealed properly.
• One last note, if you have any shrimp or small snails, they will try to climb up to eat the algae. I discouraged this by turning up the water flow.
