Speed test tower with notches

thingiverse

I've created a remix based on the Ender 3 calibration files by TeachingTech and the Speed test by poddy71. I removed the writing from poddy71's file and added markers every five millimeters instead. The tower is sixty-five millimeters tall. If you want a different height, you can use your slicer to cut smaller pieces from the STL or make your own tower using the included Fusion 360 file.
