EXTENDED G29/G923/G920 CLAMP

The redesigned clamp offers a similar fit to the original G29 part, but it is approximately 20mm longer and may fit slightly more easily due to reduced thickness in some areas. Despite these changes, the clamp remains sturdy during regular use. The part was 3D printed with PETG filament, using 20% infill, a 0.3mm layer height, and no supports required. For installation, fully disassemble the steering wheel, remove the cover, and reuse the original plastic bolts from the factory clamp. 

The model has two versions: M18 (I am currently using the M18X2.5) and M16. The factory bolt appears to be M16X2, so you would need an M16 Tap. However, I don’t have one, so I use the M18 version, which works fine until you overtighten it.

The test model includes versions for M18, M17, and M16 threads, editable file is provided you can modify it yourself if needed. Orientation during printing is critical: if you print the model lying flat with the hole facing upward, the hole will be true and round. However, if printed flat on its side, the hole may become slightly oval, making it difficult for the bolt to fit properly. For this reason, I added the M18 version, which better matches the size of the M16 hole.

Alternatively, for the best tolerance, print the M16 model standing upright with supports. This will produce a very accurate hole, but it requires more time, material, and reduces strength due to the orientation of the layers.

Overall, the best option is to print the M16 model and use an M16 Tap.
