Minimalist Document Organizer - macOS Folder Style

# macOS Folder Desk Organizer - 2-Slot Invoice Tracker

A desk organizer inspired by the classic macOS folder icon — but with a purpose: track invoices and receipts through a simple two-step workflow instead of letting them pile up.

## The idea
Two separate slots, one clear workflow:
- **Slot 1**: invoices/receipts submitted to your health insurance
- **Slot 2**: invoices/receipts submitted to your private/supplemental insurance

Move a document from slot 1 to slot 2 (or wherever fits your process) and always know at a glance what's been submitted where — no more digging through a drawer to check if something's already been filed.

Of course, the two slots work just as well for any other paperwork you want to separate — mail vs. bills, personal vs. work, "to file" vs. "filed" — whatever workflow makes sense for you.

## Features
- **Two-slot design**: built-in workflow, not just storage
- **Iconic silhouette**: the classic folder shape, reimagined as a functional desk object
- **Minimalist & stylish**: fits modern desk setups and home offices
- **Fuzzy skin finish**: a soft, textured surface that gives it a more premium, less "3D-printed" look
- **Single print, no assembly**: prints as one piece, no supports required

## Dimensions
- Width: 160mm
- Height: 130mm
- Depth: 40mm

## Print Settings
- **Material**: PLA or PETG both work well
- **Fuzzy skin**: adds noticeably more print time, but gives the surface a much more refined, matte, non-plasticky finish — worth it for a desk piece you'll see every day
- **Layer height**: 0.16-0.2mm
- **Infill**: 15-20% is enough (mostly flat panels, not heavily load-bearing)
- **Supports**: not required

## Notes
Started as a simple fix for our own paperwork chaos (health insurance vs. private insurance claims), but works for any two-pile system you need on your desk. If you come up with a clever use for the two slots, let us know in the comments!
