Still working on it. It swim pretty decent but definitely need adjustment. It was swimming only to one side so I had to bend the tow eye to the other side. That was on the original version where there's only the front chamber. I also use two double hooks instead of treble hooks so it is a little lighter in weight. I've added a second air camber to the rear between the belly and rear tie on. The reason for this is to be able to add more weights to the lure while still keeping it afloat.

For largemouth and smallmouth bass but it's a pretty big bait (4.5"). You may want to scale it down a little bit and use a drill to enlarge the tie on eye holes. It might work really well for you if your area has a lot of BIG bass.

Length is 4.5 inches (114mm) and volume is 59.9g/cm3
My print setting is 4 walls and 5% infill which gives me about 30g in weight with a pause at layer 138 (22min mark) for the front weight.

If you're aiming for 5% below the volume of the lure, aim for 56.9g in total weight.
First add the twisted eyes, split rings, and hooks you are using.
(For me, large bait is 12.5g, med bait is 5.1g, and small bait is 3.9g)
If i slice it at the above setting 4walls/5%infill @ (30.22g), and use med hooks/split rings/twisted eyes (5.1g), I can add 21.58g of BB that will FIT.

If I slice it at 5walls & 15%infill, it will give me 36.05g, I can add 15.75g of BB.
