Bollie roller for carp fishing

💬 Summary 

A manual Boilie Roller designed for the efficient production of round carp fishing baits. The system features a grooved rolling surface and a handle for comfortable operation. The design allows for the simultaneous rolling of multiple baits and is fully scalable in the slicer to achieve different bait diameters (16mm, 18mm, 20mm).

📝 Description

 This model is a simple yet effective tool for creating perfect spheres from bait dough. The main unit features semi-circular channels that shape the dough sausages into round boilies. It is designed to be sturdy and easy to clean.

Size Scaling Guide: The base model is designed for 20mm boilies. You can easily achieve different bait sizes by resizing the model in your slicer software:

100% Scale = 20 mm boilies

90% Scale = 18 mm boilies

80% Scale = 16 mm boilies

The set includes the main rolling block and a handle that can be attached to facilitate the sliding motion required to roll the baits.

💡 Assembly & Usage:

Assembly: Glue the handle to the back of the top rolling block (if printed separately) to allow for a firm grip.

Preparation: Extrude your bait dough into "sausages" that roughly match the diameter of the grooves.

Rolling: Place the dough strips across the bottom grooves, place the top roller over them, and slide back and forth until round.
