Z-Antiwobble

This is a version that is flipped "upside down"
To give more vertical space and a cleaner look.
Slot for clamping is a bit wider. And the holes is 3.5mm for easier accommodation
of the m3 screws. Was going to do insert for the nuts. But risk is that someone have nuts that won't fit.
Same bearings as the original design.
Update1
Did produce a pair. Worked nice. with some minor scraping with a exactoknife. It got a nice fit for the bearing. No need to glue. the holes for the guide rod,
