Sapphire Plus heat bed support align tool

thingiverse

When assembling the Sapphire Plus at some point you get to the chapter "Install the Hot Bed Support". The manual states "Fix it to the sliders on both sides and keep it horizontal and not skewed". What they mean is you have to mount it on the sliders but keep them perpendicular to the linear rails. If you keep them horizontal to your table and your table is not 100% horizontal then you end up with a skewed fix. That may result in heat bed that cannot be leveled. What you need is a simple tool that helps aligning the heat bed support perpendicular to the rails. Only one thing: you need a 3d printer to make the tool...
