Horrible design. The Tool is nice and all, but the hole designed for the M3×30 to thread into was extremely badly dimensioned and had absolutely no grip. The screw should have been a few mm longer or the hole just better designed. As a matter of fact, why would you not use heat set inserts? Really horrible experience and caused me to have to spend another 4 Euros+ shipping as I had to get a replacement printed part. (That, and another SINGLE pulley for 6! euros but that was on me because of the Threadlock fix I attempted) If there is ever a revised version of this printer this is absolutely a part that 100% needs changing.
Following the directions in the next steps I needed the screws as they are listed on the preparation page and shown in the pictures (4x M3x6 and 6x M3x10).
