3D model description

The Cuttlefish Reaper Mold

This is a two piece injection type mold for making a soft plastic Reaper type fishing lure. This is a modified version of the Reaper I did before and the tail of this bait was model after a Cuttlefish fin hence the name. This is just a unique lure I came up with to test out a crazy wavy split line on a 3d printed mold. It turns out that it works quite well.

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 not know the longevity of a printed mold. Your results may vary depending on brand/type of filament used.

4/15/20 - Per request I added master molds for creating Molds from silicone. (I have net tested these so if there are problems let me know.)

8-29-20 - Added a thinner version of the tail to try and get more ripple action of the tail.

IF there are any problems with the STL's or you have questions please let me know.

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.
