Opel / Vauxhall Omega B Reverse Gear Lever Collar – Gear Shift Reverse Lockout Replacement

3D-printable replacement reverse gear lever collar / reverse lockout lift sleeve for the Opel and Vauxhall Omega B manual transmission gear shifter. This is the part located directly below the gear knob that the driver lifts to engage reverse gear. After many years of use, the original plastic component can become worn, cracked, loose or completely broken while the rest of the gear-shift mechanism remains functional. Instead of replacing the complete gear lever assembly or searching for increasingly scarce used Omega B interior parts, simply print a replacement and restore the original reverse-selection mechanism. Designed to reproduce the characteristic shape of the original Omega B reverse lift collar while remaining straightforward to manufacture with an FDM 3D printer. COMPATIBILITY Designed for: Opel Omega B Vauxhall Omega B For manual-transmission gear lever assemblies using the lift-up reverse lockout mechanism shown in the reference image. Omega B vehicles were equipped with different manual transmissions and shifter configurations depending on engine, production year and market. Please compare the shape and dimensions of your original reverse gear collar before printing to ensure compatibility. PART FUNCTION This is not the gear knob itself. It is the movable collar / sleeve positioned underneath the gear knob. To select reverse, the driver lifts this component upward, allowing the gear lever to move past the normal reverse lockout.

PA12 / Nylon — BEST CHOICE ⭐⭐⭐⭐⭐ Recommended for maximum durability due to its: ✔ Excellent toughness ✔ Wear resistance ✔ Fatigue resistance ✔ Good resistance to repeated mechanical operation PETG ⭐⭐⭐⭐ A very practical choice for most home printers. PETG provides good layer adhesion and sufficient toughness for this type of interior mechanism. ASA ⭐⭐⭐⭐⭐ Excellent automotive material with very good resistance to the high temperatures that can develop inside a parked vehicle. ABS ⭐⭐⭐⭐ Another strong option for automotive interior applications. PLA ⚠️ PLA can be useful for checking dimensions and fit. PLA is not recommended for long-term use, particularly in vehicles exposed to high summer temperatures. Suggested settings Layer height: 0.12–0.20 mm Walls: 4–6 Infill: 50–80% Top / Bottom layers: 5–6 Scale: 100% Because the component is repeatedly pulled upward during reverse selection, prioritize strong layer adhesion and sufficient wall thickness. INSTALLATION Remove the gear knob and any necessary surrounding trim according to the configuration of your Omega B shifter. Remove the damaged original reverse-lockout collar and install the printed replacement in the same position. After assembly, verify that: ✔ The collar slides smoothly up and down ✔ It returns correctly after use ✔ Normal forward gears can be selected normally ✔ Reverse remains locked out until the collar is deliberately lifted ✔ Reverse can be selected smoothly after lifting the collar ✔ The replacement does not bind against the gear knob or gaiter Do not force the gear lever if the new component does not move freely. Minor sanding of contact surfaces may be necessary depending on printer tolerances. IMPORTANT SAFETY CHECK Because this component forms part of the reverse gear selection / lockout mechanism, correct operation must be verified before driving. The vehicle should not accidentally enter the reverse gate without deliberately operating the reverse-release mechanism. If the shifter mechanism itself is damaged or excessively worn, repair that problem rather than relying on the printed collar to compensate for it. RESTORE YOUR OMEGA B SHIFTER The Opel Omega B is now old enough that many small original plastic interior components are becoming brittle and increasingly difficult to source in good condition. A broken reverse collar should not require replacement of an otherwise functional gear lever assembly. Print → Replace → Restore the original reverse selection mechanism. Perfect for: Omega B restoration Manual gearbox repair Gear lever restoration Reverse lockout repair Classic Opel maintenance Important: This is an independent aftermarket 3D-printable replacement and is not an original Opel, Vauxhall or GM component.
