I added a vacuum hose attachment to DIY3DTech's project. It is a separate piece that you glue on. (Thank You CA Glue and Accelerant...)

The vacuum port is tapered and sized to match the adapter in this ridgid hose kit: https://www.homedepot.com/p/RIDGID-1-7-8-in-x-7-ft-Tug-A-Long-Vac-Hose-for-Wet-Dry-Shop-Vacuums-VT1720/312574446

(1-7/8 in. x 7 ft. Tug-A-Long Vac Hose for Wet/Dry Shop Vacuums)

The g-code files are pre-sliced for an Ender 3.
