Fuel tank filler neck rubber for Socata Rallye
Description
The filler neck rubbers on my 1966 Socata MS893A Rallye needed to be replaced so I designed my own, to be printed in TPU. TPU is oil/gasoline/ethanol resistant and my not-so-scientific tests on the material I used (3DPrima EasyPrint Flex TPU 95A) indicate that it meets flammability UL94 V-1. It's designed from the dimensions on my 1966 MS893A so I can't guarantee that it fits all Rallyes. Feel free to adjust dimensions if needed, Fusion360 file (.f3d) attached. - New version v3: Reduced wall thickness from 2.5 to 2 mm for better flexibility. STEP file added.
