Build your own Railcore

The best way to get started is to thumb through the Assembly Instructions and Bill of Materials first. Then, your options are to self-source using the BOM, or purchase a kit. Kit options:

• https://www.filastruder.com/collections/railcore (US-Based, kits are comprised of exactly the parts on the BOM)
• https://hightemp3d.com (EU-Based, kits may not be comprised of the parts on the BOM)
