Land Rover Defender LT230 oil seal seating tool

This is a simple tool, created to fit the oil seal on my Land Rover Defenders 4x4 differential transfer gearbox.
The proper Land Rover tool costs about £86, and the 3D printed one here is about £1, depending on fill percentage, and filament type.
I printed this in PET-G, at 250C, bed temp 50C, 0.4mm nozzle, 50mm/sec print speed.
Fill was 50%, and for strength I used 2mm shell thickness..
I know it's a simple thing, but it works, and I needed one!
