This bed level test measures 185mm x 185mm x 0.4mm thick.

Check and adjust you bed level before printing actual parts. Using this to set your bed will ensure maximum adhesion. The thickness is 0.4mm, which will translate to 2 layers at 0.2mm layer height.

I was struggling with part adhesion and bed leveling until using this. Problem solved! I recommend setting approximate height with paper to begin with so you know you are in the right ballpark before beginning this print. I used it on my stock Ender 5 Pro.

Material: take your pick PLA, PETG, ABS, Nylon, etc

Layer height: I used 0.2mm
