3D Printed Panfish Lure Mold

3D Printed Panfish Lure Mold 1


Hey guys! Today we're taking a request from a viewer named Ryan, thanks for the idea! I had a lot of fun building this Panfish lure and this mold. If you are on my mailing list you would have already received the STL files for this mold so you can print it yourself. If you're not on my mailing list, there's a link below how to join. Ryan asked for a Panfish lure mold and sent me some photos and overall dimensions. I decided it would be a good chance to show you guys how to do multi-cavity molds in a 3D printer.

Most of the time I make molds or single cavities just because it's a whole lot easier. Also, you don't have a lot of size on a 3D printer to do multi-cavities, like a large five inch swimbait for example, but a Panfish lure is tiny it's an inch and three quarters in overall length. Let's go into Fusion 360. As you can see, the main body has this rib section and an easy way to do that is with a Taurus and then you take that Taurus and you make a pattern along the path.

So I make my initial Taurus and I get it to the right size then I draw a path which is the overall length of the body which in this case is three quarters of an inch. I just make a pattern along that path and make sure that all the Taurus’ connect and that's pretty much my body. You can see that I end up with a hole in the middle and I just make a circle and extrude that circle through the main body. I join the bodies together and that fills that in and also leaves me a little bit of extra body in the front that I can make my sprue for.

The back legs are pretty simple, I draw a single arc here and use the pipe command to extrude it out and add a sphere on the end. I’m just eyeballing sizes at this point but you want the sphere bigger than the legs then it's a simple matter of drawing another line and mirroring that leg to the other side so they're perfectly even. Then we're pretty much done with the master.

Now let's talk about building the molds. The first thing I did was try to build one giant mold with all the cavities on one side. This seemed like a great idea until I popped it into my slicer and noticed it was going to take an incredibly long time to print. I decided to print it anyways but the problem with long prints when it comes to molds is not necessarily the length of time it takes but the amount of resin it takes and the amount of times you have to refill. So I started printing this thing during the day and refilled the resin a few times. I gave it one final fill before I went to bed which I thought was enough and it turned out it wasn’t enough at all so I ended up with this wonderful mold here that is missing basically the top quarter of it all. So, that mold was a complete failure. I could have printed it again and gotten better results if I would have sat there and babysat it, but I decided I didn't really want to wait 19 hours and a redesign was in order.

I just pop into Fusion 360 and pull the timeline slider back to where I had my original masters but I hadn't constructed the mold yet. I simply repositioned the masters to be side by side and slightly offset, rebuild my mold box and put my sprue hole in there. This mold only took nine hours to print and it came out pretty perfect, I have a little bit of pull away on the bottom here but it's still going to shoot.

Speaking of shooting, let's see how the Panfish lure molds came out. I decided to shoot some chartreuse and some red and I also did a little bit of a laminate here on a few on the legs. They came out absolutely perfect, I can't wait to go fishing with these lures. Right now, it's raining so I’m going to have to save that for another video but I hope this gives you some good ideas on how to do multi-cavity molds with a 3D printer. It's pretty straightforward but you want to keep your lure size down. If you're interested in a full detailed rundown on mold making, lure design and Fusion 360, I have a playlist that will fill you in for when I go fishing with this lure.

 

 

Alright guys, get that lure out of your head and onto your line.
