4-Inch Tube Cutting & X-Pipe Marking Jig Set | 7 STL

Build repeatable exhaust, turbo, intake, and X-pipe sections from 4-inch OD mandrel-bent tubing. The upper and lower guides can be used for Sharpie layout or as a bandsaw cutting jig.

INCLUDED

• Upper and lower jigs for 4, 5.5, and 6-inch centerline radii

• Alignment key indexed in 5-degree increments

• X-pipe marking feature

• Recesses for optional 8 x 2 mm magnets

• Seven STL files only — no STEP, SolidWorks, or other CAD source files

PLA works for marking and light shop use; PETG provides greater durability. Calibrate dimensional accuracy and verify fit against the actual tubing and bend radius before cutting.

Digital STL files only. Tubing, magnets, and printed parts are not included.
