MendelMax 1.5 X-Ends with cilindrical leadscrew nut

I am looking for a MendelMax 1.5 X-Ends design that will fit LM8 and a cilindrical lead screw nut of 17-18mm outer diameter. I am not using this specific lead screw, so I would rather use an already proven design, then starting a design from scratch. So, if you have a thingiverse link for it, feel free to share

The nut OD can be anywhere between 17mm and 25mm, as it has not been machined yet. It can be machined with a flange at the bottom also. All smooth rods are 8mm with LM8UU.

Thanks
