Project IJ Rock Slider STL Pack

Design and Fabrication Files for Steel Rock Sliders

Take your Project IJ build from printed prototype to full metal fabrication.
This STL pack includes all the 3D-printable fixtures, templates, and jigs needed to build the Project IJ rock sliders when used in combination with the laser-cut steel parts available through SendCutSend.

What’s Included

• STL files for:

  • Driver- and passenger-side fixture jigs to hold the tubes and plates during welding

  • Bend template to match the correct curvature of the 3/16" outer tube

What You’ll Need

To complete the full set of steel sliders, you’ll also need:

• Laser-cut steel parts — available through SendCutSend (https://marketplace.sendcutsend.com/p/CF271003/project-ij-sliders)

• 3/16" diameter steel tube or rod

• HD Tube Bender — the bend template and geometry are calibrated for my bender and will fit best when using it. (https://harleydesigns.com/store/hd-bender-for-316-tubing)

  🔧 It’s highly recommended to use the HD Tube Bender to ensure correct alignment and fitment.

Assembly Overview

1. Bend your tube using the provided template and the HD Tube Bender.

2. Place the bent tube and laser-cut plates in the printed jigs.

3. Tack-weld the assembly together.

4. Final-weld, clean, and finish as desired.
