Clean the build plate before printing, and allow it to fully cool down before taking it off the build plate smooth PEI plate is recommended. Different keyboard fidgets have different sizes; I modeled using normal sizing. If it doesn't fit, you may need to change the size or sand it, which may affect its ability to click or move properly. If It dosent click, you may be using bad filament, pulled it off the bed too early, or not leveled. You may have to make a few to get one that works perfectly.
