Pusher for the pesky driveshaft seals on the GM F23 gearbox differential casing. It is a cheap alternative to the KM519 official tool.
Hexagonal shape is made to mate with a 32mm socket, you can add some electrical tape to it to make it a snuggier fit.
When installing the driveshaft seals, make sure to put them in the freezer for a couple hours, and try to get in as straight as possible, with some gearbox oil on the seal lip to ease it in.
Don't try to hammer directly on the 3D printed part, it will crack. If you hammer vigorously with a rubber or plastic maller on the socket or an extension shaft, it should eventually drive the seal in quite nicely... rather many vigorous taps than one bull strength whack, however.
Initially those were planned to be single use only, but if you are moderate they can last quite a while, the original one printed at 80% infill has done 4 driveshaft seals and is still going.
The first seal may take longer to fit in, as the infill inside the pusher may need to "squash" a little bit.
