Description

Press for making 40 mm diameter groundbait balls for carp and groundfish.

The design of this ball press has been carefully studied:

to be 3D-printable, even with PETG
to be sturdy and durable
to withstand the strong pressure exerted by two impatient fishermen’s hands 😉
to make balls!

It is printed in just two parts, each of which includes a built-in ball-ejection mechanism.
This means it can be 3D-printed using the “print-in-place” method.

For the listed price, you get a complete premium kit consisting of 3 parts, allowing you to create 2 different models of bait ball dispensers:

A model with a side slit for inserting hooks or small feeders into the ball
A one-piece swimsuit with no cutouts

My designs are intended for FDM 3D printing. They are tailored to meet the specific needs of anglers. They have been designed, printed, and tested repeatedly in real-world fishing conditions until optimal results were achieved.

Technical Tips for 3D Printing

Numerous tests were carried out before obtaining this 3D printable model in PETG, without support, with the internal mechanism already included in the part.
PETG recommended, ABS, ASA, PLA+.

There's no need to fill to 100%, but I recommend opting for a percentage that will support the inside of each piston, around 30% with a cubic fill for example.
Can be printed with a 0.6 mm nozzle (in my case)
At least 3 wall thicknesses

💡 Tip: once the part has been 3D printed, the mechanism may remain stuck. This is normal, don't panic 🙂
The solution is simple: use a cylindrical object with a flat edge slightly smaller than the moving part, and tap it with short, sharp strokes.
Even if you print in PETG, the part will regain its freedom... that's what tolerance is for!
