HyperCube Evolution-Y Carriage fit assistant

Thanks Scott for 'https://www.thingiverse.com/thing:2254103', The part help to setup Y-carriage, and it may help X/Y/Z carriage accuracy. You need print two of the part. The distance between the 3030 frames is 102mm due to my x rods with 10mm (x-carriage increase 2mm on each side), if you use x rods with 8mm you can modify the distance to 100mm like Scott's thing. But if you don't change the distance incase you want switch to x rods with 10mm anytime, I consider it is OK, because I haven't found any effects till now. Attached files were included the solidworks file.
2017-7-13: If you use 102mm frame distance, remenber decrease 2mm for Z rods, but the original Z rods length is still work, just feel not perfect...
