Garmin 011-02023-90 Spacer for Zumo XT

Apparently these spacers (nr 3 in picture) help with the depth of the Zumo XT on the motormount more/better.
I had forgotten mine and lost them, and now the spring loaded electric connectors were bent.
Ordered complete new motormount (011-02023-90) and measured these spacers, which are made of very thin metal.
Included 3mf, stl and stp files, with or without fillet.
