do you still have the scad files? i would need to modify your design for 10mm rods..

I guess 10mm rods simply won't fit. There's 0 clearance between those 17mm nuts and the LM8UU bearings.

i don't use the LM10UU bearings. i use SKF LBBR 10 instead, they are smaller.. so it should/could fit

Hey, I just printed these parts, cause I'm using the same TR8 17mm. I wonder how you put endstops for the x-axis on one or better both ends?

Hi, I use endstop holders for the smooth rods, like these ones: http://www.thingiverse.com/thing:30085

I have the same nuts and would like to try redesign my 5mm rods to 8mm. What ball bearing do you have for belt idling?

I use SKF 623 (3x10x4mm). that's quite small, but almost the same size as the belt pulley.

Great! would you please upload some photos of the final installation?

Done, is that OK or do you need another part?
