Car Jack Adaptor for BMW i3

Jogis Jack Adapter for BMW i3
(and presumably also many other BMWs)

It's time for winter tires, but my jack doesn't have a rubber pad, just bare metal.
You need an adapter for this.
A very special one for BMW - rectangular instead of round!

There are already ready-made print templates, but without measurements!
Of course, the first adapter won't fit my jack and the second won't fit the car!

So I quickly drew it myself.

TPU is ideal because it's like rubber.
Some people also print with PLA or PETG, but TPU is clearly better here!

The adapter consists of 2 parts because there are overhangs in the print and that's difficult with supports in TPU.

Part 1: rectangular connection for the BMW i3 (and others)
and it's 57mm x 29mm - so you can measure to see if it fits!
The height of the rectangular block is 14mm.

Part 2: The jack mount - I have a hardware store part like that.
The rubber is suitable for jacks up to 55mm outer diameter. The inner diameter is 41mm.

Print the two parts in TPU with 40% infill, connect them together, put them on the jack and have fun changing tires!

TPU compresses slightly, which creates a uniform contact surface.

Use at your own risk, of course!

After changing the tires to winter tires and after finding a screw in the winter tire, also back to summer tires, I can say that the part is still in perfect condition after use on 8 wheels, so 8x lifted.
Maybe I would print it with 60% infill next time.
