608 Bearing Idler 2mm Belt

The original design was way too loose for my 608 bearings... made it a tighter fit with one enclosed side to hold bearing from at least one face... this suited my hanbot modifications a lot better and in line with my normal use of 608 bearings... happy pritning

Ive printed it now, very tight fit, banged it in with a mallet its as firm as can be, perhaps a little going over the inside bearing hole may be necessary.
