PETG vs PLA for Fishing Lures and Fishing Gear
PETG and PLA for printed lure bodies: choose a material, follow its profile and check the finished build. Heat resistance does not validate hot-plastisol molds.

Use PLA for an easy fit check and PETG as our starting material for a lure body. The result depends on the print and assembly as well as the filament. Neither choice establishes strength, waterproofing or fishing performance.
PLA for the first fit check
Use a familiar PLA profile to check whether the body halves close, the wire sits in its channel and the hardware fits. Keep the design’s geometry and settings consistent. A successful fit check is not a water or heat test.
PETG for the next build
Prusa describes PETG as suitable for many outdoor applications below 80 °C. Follow the profile and limits for your actual filament. Do not assume a printed part will tolerate a hot car or an applied load merely because it is PETG. Drying, temperature and retraction can all affect the print.
Compare one model at a time
The SHOAL 9 cm crankbait has a parts list and build guide. The current wobbler fit-test starting point is a 0.4 mm nozzle, 0.16 mm layers, three walls and 10% gyroid infill. Use the temperature profile for your material; do not copy a PETG nozzle temperature into a PLA profile.
Record the printed mass and check the joining faces before assembly. The filament and first-print guide gives the next checks. Complete the required through-wire and epoxy sealing steps for either material.
Keep mold and hardware requirements separate
Hot plastisol and loaded outdoor hardware create different problems from a lure body. PETG is not automatically suitable for repeated hot pours. Use a mold with a separately validated material and process. Rod holders and mounts likewise need their own fit and load checks; the lure settings above are not a universal fishing-gear profile.

Can I print a lure body in PLA?
PLA is useful for a first fit check. PETG is our starting recommendation for lure bodies. Both require the specified wire assembly and epoxy sealing, followed by checks of the finished build.
Does PETG make a printed lure waterproof?
No. Material selection alone does not close seams or printing defects. Epoxy sealing is required for our lure bodies; check the finished assembly for leaks after curing.
Can I pour hot plastisol into any PETG mold?
No such claim follows from using PETG. The filament’s temperature limits, mold design and pouring process need separate validation. A lure-body print profile is not a hot-pour mold specification.
