Monoprice Maker Select (Wanhao Duplicator I3)
This print is VERY sensitive to bed leveling, since it spans the almost the entirety of a 200mm x 200mm bed. I have added a "level test" file that takes roughly 30% of the time to print as one divider, to let you know if there are any issues before taking on a full size print.
For best results, print at a .1 base layer to get a smooth appearance on both sides.
This is my "start learning Tinkercad" project. I measured a CD, and created the dividers based on that size. The 1" letter was chosen because that's how much more room I have on my shelf. The Hex pattern is to save time/filament.
