Update 2022.02.08 - Added a version without reinforcement around the mounting holes, as it apparently wasn't printing properly for everyone.

I have no idea who the original author is. I've had a printout of this flowsheet on my workbench for years, and was inspired to make a printable plaque version.

Dimensions: 12.6cm wide x 16.4cm tall, 3mm thick

Insert a pause in your slicer to change colors when the text starts.

Print with 100% infill. The only part where infill comes into play is in the reinforcement squares around the two mounting holes on the top corners. When I tried it with 15% infill, it left gaps around the mounting holes.
