$Header$

## Purpose

This project provides a transparent and reproducible cost model for the
"Filament Storage 2026" drybox project by GunplaMark.

The model is intended to answer questions such as:

- What is the out-of-pocket cost to build 1 drybox?
- How does the per-unit cost change when building 4 dryboxes?
- How does the per-unit cost change when building 12 dryboxes?
- What inventory remains after each build scenario?
- How much do filament and electricity contribute to the total?

The model accounts for:

- lot-based purchasing
- per-box usage
- printed part filament cost
- electrical cost of printing
- optional waste factor
