13mm Rubber tube cutting jig

I wanted a quick and reliable way to cut 13mm lengths of 8mm OD rubber tubing (Like this: https://www.amazon.com/gp/product/B09DKYKN13/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 ), so I whipped this up in Fusion. Not a lot to fuss about. Quick print, no supports needed or anything.

Simple enough to operate - slide tubing in, use a fresh straight razor to cut, remove piece, repeat!

.2mm resolution is fine.
