STL files for stainless steel accessories (CAD-made speargun components) to help you build and upgrade your speargun precisely. The package includes STL models for the safety strip for the AR-15 style base, trigger guard, reel mounting plate, line guide, line anchor, and ballast cap—perfect for either 3D printing (plastic mockups/fixtures) or cutting/finishing stainless marine plates. Some files may not include DXF/CAD, but you can contact me to request the missing formats.

Manufacturing settingsSuggestions for laser cutting , 316 material and 2 to 3 mm plate thickness Suggestions for 3D-printed parts in marine environmentUse stronger waterproof materials: glass-filled nylon (PA-GF) or CF-filled nylon; optionally ABS/ASA for non-load cosmetic parts.Avoid PLA (water absorption, warping, faster aging).Print orientation matters: place layers so stress is not pulling along the layer lines (especially for guards/plates).Post-processing: consider annealing (for nylon/ASA where applicable) and seal coating (epoxy coat) for extra water resistance.For load-bearing parts: print only prototypes/fit-check parts—use stainless for functional hardware.
