Getting started

Before you begin assembly it's advised that you confirm you have all the parts and tools required to complete the build. Please see the BOM for a complete list of all parts required.

Printed parts may require cleanup using a utility knife and drill.

Printed parts may have a flared edge where they were attached to the print bed. To remove this edge you can use sand paper or a utility knife to scrap the lip off. Do not cut the edge off with the knife as it may damage the part only use a scraping action or sand paper.
Bolt holes in printed parts may require reaming or drilling out to remove stray plastic. Use caution not to drill all the way through parts or to be to aggresive and damage the part.

Please work safely and observe all safety precautions included with your tools.
