It would be really helpful to include a short ended 2.5mm Allen key for the Y-belt holder and tensioner pieces (steps 27 & 29). The limited clearance made it challenging to tighten the screws with the provided ball end 2.5mm Allen key.
I ended up grinding down a spare 2.5mm Allen key to 10mm long and that worked perfectly.

Sorry... You can check if your frame is tightened correctly.
