About this 3D model

As I wanted to keep a good precision for printing, I decided to keep my 20T pulley but didn't fit with the 15*15 open beam profile. Just have to cut the low profile in front of OB1.4. Remove 25mm profile and cut it into 2 parts of 182.5mm, put this printed part in the middle and you've now got the right to put a little pulley! ;) Be carefull to turn the piece to put the open side up to print ;) Pictures to come Look at this OB 1.4 add-ons collection: http://www.thingiverse.com/Dexerit/collections/ob-14/page:1 Enjoy
