Original design by johnysmrz. I liked his idea and printed it (scaled at 103%) but the holes weren't the right size. After further inspection I determined starting from scratch would be easier (at least with my current skill set), and after a couple of attempts (5 to be precise), this is the result. Hope u like it...
Printed on Ender 3 V2, 0.2mm layer height, 20% infill as is (standing up, no scaling), 2 walls, 4 top, 4 bottom, ah, and I print at 0.5mm line width (with a 0.4mm nozzle) to make stronger pieces. No support or adhesion necessary, but u can use a brim or a raft if you're having trouble with the first layer.
One of my trial versions was with a 0.12mm layer height but there was no discernible benefit here, except the smoothness obviously. But the holes and text were identical.
(This is actually my 3rd design. I will be uploading the first 2 shortly)
