When upgrading my P3Steel with some Z-Axis lead screws I couldn't find any system I really liked. I liked toolson's X-axis system but it uses the standard threaded rod. Based the main dimensions off of MazaaFIN's Smooth X-axis, added a mounting point for toolson's Z-axis endstop trigger, and made 2 different tensioner's.
Designed for 8mm lead screws using the T8 nuts with a 17mm center-to-center distance between the linear rod and lead screw. The tensioner's use M5 bolts and nuts, one variant uses a M5 square nut instead of a hex. Everything else should be standard M3 stuff. This should work with any X-Axis carriage if it keeps with the original linear rod spacing.
Currently in the process of printing to verify it works well.
Update: Clearances are super tight on the models, Linear bearing slot is 15mm diameter, lead screw nut is 10.2mm and X-axis rod holes are 8.1mm. Also forgot to make the slot on the [x_axis_tensioner_with_pulley.xtl] big enough to get the pulley in in the first place. It might still work if you're not the using 18mm diameter toothed idler. I'll be fixing the tensioner in the next couple days and will either upload some other parts with bigger clearances or just the model file so people can adjust to their needs.
Update 2: Fixed the tensioner with pulley so it now has a opening in the back as large as the cutout, also uploaded all the solidworks files. Got it set up on my P3Steel with the two piece tensioner a few days ago and it works great.
