Inspired by https://secretsaddle.com/de/produkt/gebiomized-80mm-tool-2/
I wanted to have a caliper tool to have a reference for all my different bikes to get the same bike fitting. So I simply (re)created this little tool. Since I only have Selle Italia saddles, the width is 70mm (BRP called by Selle Italia) in difference to Gebiomized's 80mm width.
Give feedback please, I just printed it and Im gonna test it soon
