UMD Memory Stick holder

Now you never lose a spare memory stick for your PSP.
Fit for PSP model 3000 and may be 2000, but definitely not for old 1000 (fat).

__19.04.2019__: [da_berch](https://www.thingiverse.com/da_berch/about) made [version](https://www.thingiverse.com/thing:3574225) compatible with 1000 only, but for microSD.

__01.10.2019__: [Afroasasyn](https://www.thingiverse.com/Afroasasyn/about) made [version](https://www.thingiverse.com/thing:3889644) with 1 MS and 2 microSD slots.

There a two variant available:
+ one slot, easy printing;
+ two slots, print with supports.

__Update:__
I made quick and dirty print SBS(semi-flex filament) with __0.6 mm__ nozzle.
It's works as intended. A MS fit tightly. PSP has no notice that something in a tray.

##### Warning:
Models can be used with PLA, HIPS or SBS.
Layer height: 0.2 mm.
Nozzle: 0.3-0.6 mm.

If you print smaller or larger than needed, use Customizer or take a scad file.
