⬢Please prepare tools for this chapter:
⬢2.5mm Allen key(s) for M3 screws
⬢1.5mm Allen key for nut alignment
Note there are two types of the 2.5mm Allen keys. Use the longer one for screws, which are difficult to reach as this Allen key has a ball end.
You can use your own tools if you find them more suitable for the build.

April fools
This is the only step that works - the rest are all screwed up.... Don't make sense... Must have been written on a Monday after the party...

It is not our responsibility to correct bearing count and wrong size shifts. This must be done by PRUSA who are already aware of the fault - they had the time to reach out on a new letter and inform you of the problem. They have chose not to. I had put this project on hold - I have reached out to them and todate not received a fix. If this company wish to continue to grow. It must learn from its errors. You do not have to do it for them. You have a voice and there are many ways to get the message out there.
You also have the object to return the defective item. Each country has various laws on this.

Hi Bill. You have been contacted by a Prusa support guys already, so you can tell them something about yourself for better understanding of each other. Try to describe the exact issues in detail. I'm sure they will do the best they can to help you out! :)
