Did you 3D print this model?

3D model description

The Sentinel Grub

This is a four piece injection type mold for making a soft plastic 4 tail grub fishing lure. I don't think (currently) that there is a four tail grub on the market so this is quite a unique lure.

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)

This is a plastic mold so you have to be careful with your temps and injection pressure. I have never personally shot an aluminum mold so I can not tell you the difference in pressure needed but DO NOT use a lot of pressure... or 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.

Video of this mold in use and it's action can be seen at https://youtu.be/ESSYNRm5MjI I highly recommend watching this video before purchasing this model to see if it's something you can do.

The pieces of the mold are identical but I made them four separate pieces and numbered them individually so the mold always goes back together the same every time. This way if there is any warping this should (but not always) ensure the split lines stay as tight as they can.

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

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

3D printing settings

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

Layer Height = .10mm
Top Solid Layers = 15
Bottom Solid Layers = 3
Outline/Perimeter Shells = 4
Supports = I did use supports on the side of the tail piece but it my not be required.

Infill = 25%

I print the mold parts with the pins facing up. The alignment pins may need sanding and I usually ream the pin holes with a .25" drill bit to clean them up.

Print times for me were about 6 hours per piece (I printed them one at a time) so the mold takes about 24 hours of print time.
