Create solids to measure the friction force of printed for the fitting concept

Description

The hole in the bottom of the plate und the rails under are necessary to annul the effect of air pressure.
It is possible to place standard weights on the base to push it in and measure the forces. The depth gives information about the frictional forces. The wall thickness of 1.2mm allows a certain elongation.

When creating fits with a 3D printer, three effects (1-3) of four will overlap:
a) The deviation of the outer diameter of a bolt from the inner diameter of a hole
b) The frictional forces due to the roughness of the surface finish of the respective printer
c) The expansion of the material during indentation depending on material and infill
d) Shrinkage due to cooling from printing temperature to room temperature
Finally, a number of test samples must be printed so that a feeling for the fit dimensions can be obtained by manual joining. However, once these are determined, fits can also be printed very reliably.
