Thanks for the compliment.
This design is still printing well for me. What material are you using?
I use abs with a slightly higher nozzle temp to ensure good interlayer adhesion.

There are certainly good and bad filaments though.

I really love this design, it spins beautiful! I first tried the device with a nozzle width of 3mm (drilled the hole). This was too much, in combination with my groundwater pump. The wobbler is too weak for the arising forces. But with a nozzle size of 2.5mm it seems to go well. I am using 6 of these sprinklers now and have several 'orders' from family and friends.

The wobbler turned out to be particular difficult to print. When the 3 risers (legs) go over into the top part (actually the bottom), the printer tends to break one or two of these risers. A z-hop will not help.
