Gridfinity Magnet Tube Holder Half Height

I liked the shorter version but wanted to have more rounded edges on the top rather than the hard 90 degree angles so I made that adjustment and also made them exactly half the height of the tubes themselves.

This is my first remix so any constructive comments are welcome!

Thanks to MrKuenning for making these awesome holders for the tubes and to wbplomp for making the original tubes!
