Core One back leadscrew alignment tool / helper

I created an easy alignement tool for the back leadscrew of the Prusa Core One.

After I finished my build of the Core One I tweaked the front leadscrews using the little helper from user @rinkel.

That worked amazing, so I also wanted to get the alignement of the back leadscrew right.

I printed the tool in PETG 0.15mm layer height and that worked great.

Instruction:

• move the bed to the lowest position
• losen the two screws on the trapezoidal nut (I unscrewed one and tighten about two turns, then same with the secound screw)
• attach the alignement tool by simply screwing it on top of the back leadscrew
• tighten the screws on the trapezoidal nut slowly (small steps alternately between screws)
• remove the tool

I hope this tool is as helpful for you as it is for me.

Happy printing! :)
