Test Object #001

thingiverse

A fairly small test object meant to test low z-layer height resolution. 30mm diameter disc base. Top is divided into quadrants of different heights: 0.5mm, 1.0mm, 1.5mm, 2.0mm, and 2.5mm The 0.5mm region and the 2.5mm region share the same quadrant. They are separated into a triangle and a arc wedge. The 1.00mm region contains a column with a cone on top. The column is 5.0mm tall. The cone, 3.0mm diameter base, on top is another 2.0mm taller than the column. The top is a 1.5mm diameter circle. The 1.5mm region contains a hexagonal pillar with a smaller hexagonal cavity rotated so that the points of the inner hexagonal space face the midpoints of the walls of the external hexagonal surface. ~6.4mm wide external face to external face. 7.4mm external point to external point. Internal hexagonal space is 5.6mm from inner point to inner point. ~4.8mm from inner face to inner face. The hexagonal column is 5.0mm tall from the surface of the region. The 2.0mm region contains a cone where the top is slanted 30 degrees. There appears to have been a modelling error on my part, so when sliced, the STL reflects some errors in one of the corners. The object was modeled in Google Sketchup and exported to STL format(mm dimensions, ASCII). STL was exported via the Ruby STL import/export extension. Slicing for my own printing done via Kisslicer. 3d Printer for my test prints is a PrintrBot Simple V2.0 printer: wooden frame, spectra fishing line for x/y. 1/4" ACME threaded rod for z-axis. Fan for hot end. Bigger fan for cooling extruder. Minor mod for filament feed to not catch. Instructions Just download either the Sketchup file to export your own STL, make changes, etc. Or download the STL I already exported. Run through your slicer of choice, and print with your printer and settings to determine whether things print as you expect.
