This is a free model of arone to be used with X or + builds. It has universal mounts for most typical board sizes, and you use 3mm-hex-head screws & nuts to put together.
Biggest part (arm) is made specifically for Skriware printer when put across the table (45 deg.) with 1 cm clearage.
Let me know if you want the easiest build that will work with this quad ;)
Enjoy, free word!
