TMRC Reaper 47 — STL Pack

Large-Scale Quad Outboard Platform

NOW AVAILABLE FOR 250 × 250 mm BUILD PLATES. The pack now includes a version segmented for 250 × 250 mm printers alongside the original large-format (Kobra 3 Max) files.

The Reaper 47 STL Pack is a large-scale RC boat hull and component set designed for builders who want an aggressive, high-power platform optimized for quad outboard configurations and large-format 3D printing.

Built for experienced builders who want full control over power and setup. This is not a beginner platform.

Printer Compatibility & File Preparation

The Reaper 47 STL Pack was originally designed and pre-segmented for the Anycubic Kobra 3 Max, allowing the hull and components to be printed efficiently with minimal additional preparation. A 250 × 250 mm version is now included so the Reaper can be printed on standard-size printers as well.

• Large-format files optimized for Kobra 3 Max build volume
• 250 × 250 mm files pre-segmented for standard build plates — more sections, more assembly
• Parts are pre-sliced to maximize strength and print efficiency
• Printers smaller than 250 × 250 mm may require additional cutting or re-segmentation of parts
