About this 3D model

I'm using the X-idler http://www.thingiverse.com/thing:1919544 from Leo_N and want to upgrade the Anet A8 to a E3D bowden setup. I used this X carriage http://www.thingiverse.com/thing:2166790 from HipoxiK, but had a few problems. The changes I've made (as you can see in the 3rd picture): Add a X Endstop support, because it didn't always switch and the x-carriage crashed several times against the X-Idler. Another problem was the belt holder. It didn't hold the "softer" GT2 belt, neither the original Anet A8 belt. So I reduced the distance. Don't know, if the original belt fit into the belt holder. The belt holder has not the correct height for the X-Idler from Leo_N. I increased it by 2mm. This is the belt I'm using with much better results: https://goo.gl/yXBLgi How to support me?
