Good design, fits very well and uses not a lot filament, but print profile is just bad, why grid infill? My nozzle was scratching all the time, thats why I have strange walls
but anyway good job!
Grid infill just because that was the default in the slicer, it looked fine, and given the use case it didn't really seem like something that needed a lot of tweaking. I don't recall having any scratching issues, but I printed mine with matte PLA, which is extremely forgiving.
