3D model description

This is a mold to make two different sized triple tail grubs for fishing. The lures are designed to match 1/16 and 1/8oz jig heads and the finished baits if stretched out are about 3 and 3.5 inches long respectively.

There are two different version of the mold included.
The 4 Cavity mold requires 6.5" x 2.5" print area for each half.
The 12 Cavity mold requires 7.0" x 6.75" print area for each half.

These are 3D printed plastic molds 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.

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 these molds in PLA+ with the following settings
(You'll have to experiment with what material and settings work best for you.)

Filament = eSUN PLA+ Temps = 215/60
Layer Height = .20
Top Solid Layers = 8
Bottom Solid Layers = 3
Outlines/Perimeter Shells = 5
Infill = %25

Hello, what is the approximate amount needed in milliliters to fill the 12-cavity mold or what is the capacity of the injector that you recommend? Thank you

I did the calculation in Fusion 360 and the amount need to fill the mold looks to be under 2oz so a 4-6 oz injector should work fine. I'll double check this and try shooting it with my 4oz Injector and make sure it's enough and get back to you later.
