For desired size scale accordingly for a 2-inch bait scale the molds to 1000%
for 4-inch bait scale molds to 2000% and plunger to 200% and so on...

Currently having a friend test for any flaws should be confirmed within a week or so whether it works.

all you need is 4 m3 bolts or 1/8th in bolts and some soft baits to melt down or bait making materials.

Print both halves and the plunger and you should be set.
