20x20x20 calibration with a twist

thingiverse

This is a variation of the standard 20 mm calibration cube. The base is a 20 mm x 20 mm x 10 mm solid block with a central hole. The two pegs are integral components. One cylinder bears the number 3 and has a diameter of 9.7 mm. The other cylinder has a diameter of 9.8 mm, featuring the number 2 on top. Ideally, both cylinders should fit into the 10 mm diameter hole with ease. The design includes a thin wall frame with a height of 4.5 mm and a length of 10 mm on top of the block. The entire block measures 20 mm in height. This test cube aims to challenge multiple printer capabilities simultaneously. Instructions for printing this design can be found below. The print settings I used include 0.2mm layer height, with the first layer set at 100% and a 20% honeycomb infill pattern. Two vertical shell perimeters are specified for each solid layer of the object. The top and bottom layers utilize three shells instead. Extrusion widths were kept default except on the first layer where they are increased to 100%. The extruder temperature was set at 210C while using a bed temperature of 60C with PLA material.
