Parametric Print-in-Place Tolerance Test

Parametric Print-in-Place Tolerance Test

No-nonsense approach:

• Use Customizer for creating a test part just for the tolerance you need
• Small and quick to print
• Adjustable parameters
• Clean design to facilitate accurate measurements
  -- no elephant foot
  -- no top layer overhang
  -- square so you can check x/y axes separately

• OpenSCAD source included so you can verify the design!
  Example STL has a bolt edge length of 8 mm and a tolerance of 0.25 mm.

  I designed this after trying out some popular existing tolerance tests, which highlighted the problem but having all sized in one big part were really wasteful and slow for re-printing them again and again to check the results of tweaking the printer.

  The "waist" of my design makes it a bit quicker to print without sacrificing bed adhesion and mechanical stability.
