**NOTE:**

- The first tab is for the total inventory. This is what you will realistically spend.

- The second tab is for the used inventory. This is the actual cost of the printer.

- The third tab is the analysis, allowing you to see the breakdowns of the printer by category.

**SOURCING TIPS:**

- Many of these items can be found cheaper elsewhere, sourced locally, or reused from parts you
  already have in your workshop. The listed prices are a guide, not a requirement, so shop around
  before buying.

- For the Amazon links specifically: these sellers frequently go out of stock or have long shipping
  times. Many other sellers on Amazon offer the exact same item, so if a link looks unavailable or
  unreasonably priced, look around for an alternative. If you find a better link, feel free to share
  it in the `Discord <https://discord.com/invite/patduYdnSN>`__ so others can benefit.
