Range Finder Card V2.5The first of the “Functional Card series”I tried to design better range finder card but it&#39;s harder than I thought (Because I&#39;m bad at math) The card only supports the arm length of 70cm. Because:1. people with 70cm arm mostly downloaded the V2 version.2. This version is not meant to be complete version of Range FInder Card.I&#39;ll design final version of the Range Finder Card that everyone can use. [Assembly]Slightly bend the card and put the slider in [How to Use] For 5m object, read the upper scale, for 170cm object, read the lower scale170cm object: average adult person.500cm object: street lights.<img src="https://makerworld.bblmw.com/makerworld/model/DSM
