3D model description

This is a single cavity Fishing Tube Bait Mold. This mold allows you to make a complete tube baits in one shot. The legs are formed during the injection process and there is no need to cut them afterwards (just carefully peel them off the insert.) This makes for a tube bait with near perfect duplicate legs. The finished lures are about 3.25 inches long.

This mold is meant as a test mold for my larger 6 cavity version to see if your printer can handle it. A printer with high tolerance is recommended or you may not achieve the proper results if the insert doesn't fit correctly in the mold halves. Even with a good printer some flashing may result.

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.

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% (for mold) 80% for Insert. (an 1/8" steel rod can be inserted into the Tube Bait Insert piece to help keep it from warping from the heat of the injection plastic.
