Ultimaker X,Y Blocks Featuring Quick Removal of Gantry

I have developed this bearing block especially for my Larger Ultimaker.
It features a quick way of removing the gantry by simply removing 2 Cap head screws on each block.
On the underside it has a belt clamp which is in two parts as I have open ended belts.

I have added a few removable pieces on the main block due to overhang while printing.
I would recommend printing with Brim
