Dimensional Accuracy and Overhang Test Object

Model Description: This test object features four 100mm diameter hoops positioned in the XY, YZ, XZ, and XYZ planes. Each hoop is 10mm thick and includes 7 holes ranging from 1mm to 7mm in diameter, as well as square cutouts with a diagonal of 6mm.

Purpose: The model is designed to assess your 3D printer's dimensional accuracy across all axes and to identify potential over-extrusion issues.

Construction Features: The XYZ hoop is oriented at a 45° angle. A critical aspect to note is that the 1mm hole may become filled if over-extrusion occurs. The YZ and XZ hoops may experience drooping at the tops, while the XYZ hoop is less prone to this issue.

Printing Recommendations: It is advisable to print without supports. Pay attention to the cooling capabilities of your printer, as insufficient cooling may lead to drooping walls. Ensure the nozzle is clean to avoid negative impacts on print quality.
