In order for my flange-bearings to fit into the Gantries for the awesome build over at: http://www.thingiverse.com/thing:811271 I had to modifiy the size of hole/s for the bearings and rods. See the image for dimensional details. It is the same changes done to all pieces. I have added 1 (for now) "extended" version of one of the gantries. It is clearly named. A Photo is also added. Gantry-X-axis-back-left-modified-extended Extended the Gantry in both ends to allow for mount/dismount of the Gantry after assembly. Can remove it without first removing endstop. Space for the use of washers.I'll recommend printing these with proper infill. Like 100% to make them to last. You do not need to scale these as my work on them did that.
