Make your sim rig look as good as it performs. These aluminium profile end caps seal the open ends of T‑slot extrusions, shielding them from dust, moisture and debris while eliminating sharp edges . This not only prevents wear and tear on your cockpit but also enhances safety for you and anyone around your rig .

Why You’ll Love Them

• Safety & Protection: Durable caps cover the raw ends of aluminium extrusions to eliminate sharp edges and to keep dirt and moisture out . This helps extend the life of your rig’s frame and prevents accidental scrapes .

• Clean, Professional Finish: A neat end cap gives your sim rig a polished look. Add a pop of colour that matches your wheel rim, seat belts or lighting for a cohesive setup.

• Perfect Fit for Popular Profiles: Designed to snap securely into 40×40 mm, 80×40 mm, 120×40 mm and 160×40 mm aluminium profiles (4040, 8040, 12040, 16040) commonly used in sim rigs and 3D‑printer frames.

• High‑Quality 3D‑Printed Construction: Each cap is printed from high‑strength PETG/ABS for long‑term durability. The smooth finish resists scratches and UV‑induced fading, and the tight tolerances ensure a snug, rattle‑free fit.

• Easy Installation & Removal: The press‑fit design allows the caps to slide onto the profile ends without tools . When it’s time to reconfigure your rig, insert the short end of an Allen key under a corner and gently pry up to remove the cap.
