Square Peg and Hole Fitment Test

thingiverse

This print serves to determine the necessary spacing between two printed components. The primary block measures 5mm x 5mm in size. Holes on the pegboard vary as follows: 4.8mm x 4.8mm, 4.9mm x 4.9mm, and so forth, up to 5.8mm x 5.8mm. In my particular print, a 5.1mm x 5.1mm slot (0.05mm clearance on each side) provided an excellent, snug fit - ideal for permanent connections. Meanwhile, a 5.2mm x 5.2mm square (0.1mm clearance per side) offered a good all-purpose fit.
