Adhesion Test Disk

In my humble opinion a bed leveling STL is pointless. Why? Because with most prints you can identify leveling issues from the skirt, brim, or raft within the first five minutes of printing.

I learned 3D printing on a $99 X1 with no heated bed.

THE FATAL FLAW OF MOST PRINTS IS ADHESION.

I use water based school glue sticks religiously.

This print is designed to test your adhesion. I place one in the center and four in the corners. This equates to a two layer print in about 10 minutes costing one gram of filament.

The disk is designed to make the first layer a series of dots, then they are connected by a continuous circle on the second layer. Adhesion problems will result in total and obvious failure.

Calibrate your bed with more heat or more glue. Once you get a successful print scrape the tests into the garbage, spray your surface with a light mist of isopropyl alcohol, and print that file that's been giving you trouble.

If this print helps you interact with me. M
