small wall mounted tool holder

I created this tool holder for a 12 piece needle file set from Harbor Freight. It is plenty sturdy and allows wall mounting to keep my files within reach. I printed with .3mm resolution at 190 degrees c, 50mm speed and 60mm retraction speed. The bed is also heated at 50 degrees c. This is my first actual 3d printed project that I have designed, so any tips are welcome.
