As seen stuck in the reeds at Freshwater Lagoon in Humboldt!
Small Egg Float models. I have a way of unintentionally using these to decorate tree branches.
I use these on ultralight spinning gear to cast dry flies, wooly buggers and small jigs.

Prints with no supports and minimal waste.
Uses 50% infill to float, but still retain good weight for casting. I find these to be perfect weight to cast for a 2 to 4 lbs ultralight setup.
 

The default profile will print 6 egg-bobbers with a colored stripe. Does not require supports.

Add eyehooks on either ends to attach line and leader.

The eyehook screws I used are 16x7.5mm [ https://a.co/d/cw17O1R ]

General 3d Printing Tips

• Make sure your printing plate is clean! Oils from your skin will cause adhesion issues for your prints. Regularly wash your print plate with a detergent like Dawn and avoid touching the surface when removing prints from the bed.
• If it's an option on your printer, always opt to level the bed before each print. If you have to perform this manually, make sure you do this after every few prints. It takes a bit of time and patience, but it's a fair trade for reliable prints.
• Ensure bed and nozzle temperatures are within the expected range for the material you are printing. Temperatures that are too high or too low will affect the print negatively by causing warping, malformed layers or adhesion issues.
• Reduce your printing speed. Slower print speed is especially important for overhangs because it gives the material more time to cool as it's deposited.
