"TerraCatch - Goldsluice

TerraCatch Sluice Box

3D-Printed High Efficiency Gold Recovery System

The TerraCatch Sluice Box is a modular, high-performance gold recovery system designed to maximize fine gold retention while recreating the natural behavior of a real riverbed.
Unlike traditional smooth plastic sluices, the TerraCatch features a fully integrated stone-textured surface structure that helps create controlled turbulence, slows down heavy material, and improves gold trapping efficiency across the entire sluice.

Built for prospectors who want portability, modularity, and exceptional fine gold recovery.

Specifications
Length: 70 cm
Width: 19 cm
Height: 9 cm

Construction: 4-piece modular design with 3 handles.

Material Recommendation: PETG

Assembly Hardware Required:
16x M6 x 26 mm screws
16x M6 nuts
16x M6 washers

Key Features:
Natural Riverbed Simulation

The entire sluice interior is covered in a custom TerraCatch stone texture designed to mimic natural bedrock and river formations.
This textured surface creates micro-pressure zones and turbulence patterns that help trap fine gold effectively while allowing lighter material to wash away.

Extremely High Fine Gold Retention

The TerraCatch system was specifically developed for efficient fine gold capture.
Its layered geometry and textured flow channels help prevent gold loss, even with very small particles.

Modular 4-Part Design

The sluice consists of five individual sections that can easily be assembled, transported, replaced, or modified.
This makes the system highly portable while maintaining excellent structural rigidity once fully assembled.

Assembly Instructions

When assembling the TerraCatch sluice sections, it is highly recommended to apply a thin layer of silicone sealant between all connecting parts before tightening the screws.

This helps:

Seal small gaps between printed parts
Prevent loss of ultra-fine gold particles
Improve water control and flow consistency

After applying silicone:

Align all sections carefully
Insert the M6 screws with washers
Tighten evenly on both sides
Remove excess silicone if necessary

The TerraCatch Sluice Box is ideal for:

Fine gold recovery
Creek and river prospecting
Portable gold panning setups
Hobby prospectors
Advanced small-scale gold recovery systems
