The R&D process
Shape. Print. Test. Refine.
Stop guessing. Rapid prototype your swimbaits at home for dollars, not thousands. Dial in the action, profile, and weight before you ever commit to aluminum.
Shape
Design your bait
Profile editors and a component library give you precise control over every curve of your swimbait.
Print
3D print a mold
One click generates a two-part injection mold. Export, slice, and print on any FDM printer.
Test
Pour and water test
Inject plastisol, demold your bait, rig it up and throw it. Watch the action. Take notes.
Refine
Tweak and repeat
Adjust the profile, change a fin, move a hook slot. Generate a new mold and test again.
Iterate until perfect — then cut aluminum
Inside the tool
Everything you need, nothing you don't
Designer
Spline-driven profile editors
Overlay a reference photo, then shape your bait with draggable control points. Side profile, width profile, and cross-section editors update the 3D model in real-time. Add heads, fins, tails, eye sockets, and hook slots from the component library.
Mold generator
Production-ready molds in one click
Parametric mold box with alignment pins, bolt holes, and a standard 5/8" sprue port. Inspect the cavity with explode, section, and transparent bait views. Choose your printer and validate bed fit before exporting.
Ready to print
Export to any FDM slicer
Download the STL, open it in Bambu Studio, PrusaSlicer, OrcaSlicer, or Cura. Print on-edge for the best cavity finish. One mold half takes 3–6 hours depending on bait size.
Advanced workflows
For the creators who want total control
Export your bait as an STL and take it into your favorite sculpting tool. Add gill plates, scales, and anatomical detail, then import the finished model back to the mold generator. Full creative freedom with a printable mold at the end.

Getting started
What you need to pour your first bait
3D printer
Any FDM printer with a 200mm+ bed. Bambu A1, Prusa MK4S, Ender 3, or similar.
ASA or PETG filament
Print at 100% infill for strength and heat resistance. ASA for durability, PETG for easy printing.
Hand injector
Standard 5/8" nozzle. Available online from multiple suppliers. Reusable forever.
Plastisol + colorant
Bait Plastics, MF Plastics, or Dead On Plastics. One bag makes 50+ baits.
Alignment hardware
Stainless dowel pins, M5 socket head bolts, and brass heat-set inserts.
Heat source
Microwave or hot plate for melting plastisol. A kitchen microwave works fine.
