Engravinator MK1 — Buy
In order to build an Engravinator follow this bill of materials. The parts listed here are optimized for building a single unit. Please check out the BOM Guide before ordering any components.
When an item is listed as "See BOM Guide", more detailed explanation is needed. Please follow the link. This is typically because these parts are not properly priced on a permanent site or require too large an order for a single unit. Prices listed for these components are estimates.
Finally, the item counts listed here are the exact amount you need to complete the build. But nuts and bolts have a funny habit of getting lost. We highly recommend purchasing a few extras of all the nuts and bolts!

Enclosure Components
Lasers can be dangerous and you've only got so many eyes! We highly recommend installing this enclosure. If, for some reason, you hate your eyes then you can skip this section but Maniacal Labs takes no responsibility for lost vision. Seriously though, if you don't use an enclosure you MUST where safety glasses at all times!
