55338-EG00A Strut Mount Seal

thingiverse

This replacement Strut Mount Seal is designed specifically to replace the OEM seal on a 2008 Infiniti G35x, which has the part number 55338-EG00A. However, it may also be compatible with other Infiniti and Nissan models. The key requirement for this seal is that it must be printed in a highly durable material like TPU, which provides excellent resistance to oil, grease, and abrasion (https://en.wikipedia.org/wiki/Thermoplastic_polyurethane). Use at your own risk. Printing this seal using TPU should cost less than $0.15 per seal and take around 30 minutes compared to the OEM replacement price of over $30 per seal. I personally used Priline TPU with a Shore hardness of 98A, which has given me consistently good results (https://amzn.to/2HqkFK0). The OEM seal is 0.4mm thick, while this replacement seal is 0.6mm thick. When printing at 0.2mm layers, you will get a 3-layer seal. To achieve a thicker seal, simply scale up the Z-axis and ensure that there are enough bottom and top layers to create a solid print. Note that the test-fit version of this seal (pictured) is slightly different from the finalized .STL file.
