1. Put a standard 8.5’’ x 11’’ sheet of paper on the center of the printer bed

   1. see if they are more or less the same size

2. Try securing multiple, different cylindrical tool below 0.5" diameter and 6" length to the pen holder

   1. see if they are all snug

3. Run the design with multiple different input images

   1. See if the ender-3 print timer says a time under 2 hours

   2. See if the pen can makes marks anywhere in the paper’s range

   3. See if the drawings look good after they finish drawing

4. Run the drawing with the same drawing multiple times

   1. See if the drawings look similar

Fits Paper - No, software allows for it but Ender3's bed is physically not large enough. Paper must be cut down.

Grips tool - Yes, insertion system is adjustable to snugly fit tools

Finishes work in under 2 hours - Yes, most drawings take under 10 minutes depending on the amount of detail

Satisfactory Drawing - Mostly (doesn't do gradients well but does digital art and cell shading fine)

Reliability - Yes, prints consistently with repeatable results
