I loved ohmg's holder for soft tape, but mine won't fit. I believe euro\centimeters soft tapes are wider so thanks to the original author that published the .step file, I stretched the height from 17 to 20 mm and it's perfect.
I also uploaded the modified .step file so I someone needs to modify again, you can do it.
Those inner lips are a bit fragile (I broke one only looking at it) but once the two parts are combined is ok.
Even if I'm a complete novice with CAD software, I managed to modify it in Fusion 360.
