3D model description

This is a mold for injecting soft plastic ribbed grubs. It can be used to make single color grubs or a core shot/tail version with the use of an 1/8" stainless steel rod or using the third mold which shoots the inserts first.

See for a video of this mold in use.

Core Shot Ribbed Grub Mold = Fatter Body Ribbed Grub
Core Shot Insert Mold = Insert for Core Shot Ribbed Grub Mold
Small Ribbed Grub Core Shot Mold Left V2 = Same Grub with slight thinner body.

Each mold half requires at least 4" x 5.75" of bed area to print.

This is a 3D printed plastic mold so you have to be careful with your temps and injection pressure. I printed this mold in PLA+ and try to inject my Plastisol at or around 300°. (I use Dead On Plastix's brand of Plastisol) You also need to use very little pressure on the injector when shooting these types of mold. If you use a lot of pressure when injecting a 3D printed Mold... you can/will blow through the mold. Start light and work up with the pressure if you do not get a full injection or you have bubbles. It's better to have a misformed bait or two than ruin the mold.

The Video link below shows How to Inject a 3D Printed Mold, I'd recommend watching before purchasing my molds.

Even if you purchased these files that Copyright means you are NOT allowed to sell the model or any derivative of the model for economic or financial gain. For example, you cannot sell the digital model, a derivative or adaptation of that model, nor can you sell prints of the model. I do however grant permission for persons who purchase any soft bait molds to sell the rubber soft baits you make with one of my printed soft bait molds.... but again you CAN NOT sell the actual models of the baits.

3D printing settings

I print this mold in PLA+ with the following settings
(You'll have to experiment with what material and settings work best for you.)

Layer Height = .10mm
Top Solid Layers = 15
Bottom Solid Layers = 3
Outline/Perimeter Shells = 4
Supports = Not used
Infill = 25%
