This is the tower that i downloaded from the remix source, but when i went to re-download it the source had changed the file. I really liked the original version because it compares how speed impacts bridging and overhang as well as overall print quality.

I would put this into your Slicer (i use Cura) and start the speed change at the following layers or the bottom of the number, this will allow the over hang to be completely printed at the correct speed. I printed with 5% infill but it can be done with 0%. Check out the settings to make it work properly.

Layers and speed for Cura @ .2mm layer height. Further instructions are in the print settings of this post. total tower height was 440 layers.

1 - 40 = 50 mm/s 41 - 80 = 55 mm/s 81 - 120 = 60 mm/s 121 - 160 = 65 mm/s 161 - 200 = 70 mm/s 201 - 240 = 75 mm/s 241 - 280 = 80 mm/s 281 - 320 = 85 mm/s 321 - 360 = 90 mm/s 361 - 400 = 95 mm/s 401 - 440 = 100 mm/s
