The original Y_Shaft_Clamp is a bit too fiddly for my big thumbs and so I decided for a remix.
There is enough space in this place to install a larger bracket.
Just insert a M3 nut from above into the slot and a M3x12 screw from the side to pinch the axis.
Be a bit careful with your strength!
The inner diameter of the original "open frame" design by Tech2C is 8.2mm. This is a bit too tight for my "closed" design. I've changed the clamps to 8.5mm diameter.
Added clamps for 10mm axes.
Probably it also works with 30% or 50% infill ... :-)
