Thanks for replying :)

So to be sure, you suggest doing the openrail z axis mod instead of doing this anti-wobble mod?

If I may ask again, where did you purchase the Openbuilds parts in Europe? Depending on what that ends up costing I'll decide on that or the bushings :)

No, anti-wobble is a must in any case. You have to get rid of the side forces introduced by the threaded rods.
The Z axis mod is more complicated, that's why I recommend to stick with Z smooth rods but change to bearings without play (RJUM). Only X and Y Openrail.

For the X and Y I orderd parts on:
https://online-schrauben.de for all the screws
http://ooznest.co.uk for all the Openrail things
Ebay for all the heat inserts ("Einpressmutter messing" is a good search word for German area, Rampa inserts are also suitable)

I ended up with roughly 150€ for the Hardware.

Alright, I see, thanks.

I'm considering the bearings then. What do you want for them, shipping to Denmark included? :)

For Z axis only? 4 bearings + 14€ registered shipping. Hm, lets say 50€ all together?

Hi

I just wonder what length do you use for the 4mm rod pointing along the Y axis?

I just made this and i cut my y-Axis rods to about 6mm and my X axis rods to 25mm

How is your 6mm fit? would you rather get a longer or shorter one instead?

The 6mm was a bit long but I wanted some meat to take off with the dremel when I was cleaning the edges. They're more like 5mm

25mm is pretty long for the x pins, so I'll cut them down to 18-20mm maybe.
