Linear bearing

This is linear bearing I designed for https://www.thingiverse.com/thing:2629911 as I couldn't get hold of one easily at the time. I had small 2.5mm ball bearings available so made this. Seems to work pretty well but I might remake it with a threaded end and cap to avoid supergluing the cap. Also just made in tinkercad as I was just testing might do a parametric one in freecad.
