I will soon receive the OF, and I decide to buy an 80mm spindle because there is at least a viable solution in 3D printing. I put my hopes on the final share of [Hrubeskyr](https://forum.onefinitycnc.com/u/Hrubeskyr) [80mm spindle mount](https://forum.onefinitycnc.com/t/80mm-spindle-mount/3459). But seeing your beautiful 3d representation it reminded me the idea I had before to radically modify the original 65mm spindle mounting block. But I do not have the dimensions of the OF spindle support to evaluate the feasibility. In your opinion, could the current 65mm OF spindle mounting block be cut in a plane close to the rail support to accommodate the RoverCNC Solid Spindle Mount there, in a similar way to your scheme. According to the dimensions of the diagram provided [80mm Solid Spindle Mount – RoverCNC Online Store](https://www.rovercnc.com/collections/cnc-machine-components/products/80mm-spindle-mount) it would be necessary to be able to make 4 holes minimum separated by 80mm between the rail support and separated by 30mm on the height (the OF support does not seem high enough to pass the 6 holes provided by RoverCNC) Is it realistic to your opinion? ![119_661_snbmount8080_specs_940x](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/d/9/d9652c4b8cd6e526c68b49f22ec95b5a55462a6e.png) ![119_657_img_20160619_073128_940x](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/d/a/daa78abb233ada11b795c2d27240b23798bea0ee.jpeg) --- _[View the full topic](https://forum.onefinitycnc.com/t/universal-z-axis-assembly/4415)._
