Description
This is a 2-part 3D printed mold designed for casting soft plastic fishing lures.
As shown in the photos, it produces small paddle tail swimbaits. The mold halves align precisely and can be tightened with screws. I used M3 screws and heat-set threaded inserts, but you can assemble it however you prefer.
For best results, I recommend printing the mold halves in a vertical (standing) orientation... I sanded the printed mold surfaces smooth with fine sandpaper to improve fit and surface finish of the casted lures.
Features:
2-part screw-together design
Paddle tail swimbait shape
Customizable hardware solution
Easy to print and modify
Perfect for DIY soft bait makers who want to experiment with their own lure colors and materials.
