Yet another reusable bambu spool

There are multiple remixes of the original reusable spool model that feature holes like this one or this one. They try to mimic the original spool holes, but look quite different when printed, because the holes are either too small or too large. For my model, I scanned the spool with a paper scanner, then replicated the layout of the holes in a 3d modelling software based on the scanned image. The holes are close to the original, but not perfect. I assume this is, because the scanner didn't do a perfect scan, or I messed up the pattern while modelling, resulting in some holes being off-center (barely noticeable if you are not comparing them side by side). For comparison, I added images comparing this spool model (always on the left) with the above-mentioned remixes and the original one. To get a smooth surface, I recommend using a smooth pei plate:
