I made this to hold my posca pens since I couldn't find any models that would hold multiple different sizes of posca pens.

This model perfectly fits up to 6 1m pens, 20 5m pens, and 3 of the large 17k chisel tip markers.

I printed with very minimal supports, just because the bottom edge is slightly curved, I also used 10% infill since there is no real need for this model to be super strong and it dropped printing time by an hour.

This is the first model I've uploaded, feel free to leave feedback!

Happy printing!
