About this 3D model
This device is designed for a JYP 290 chineese Lathe (Same as Bernardo). It supports the "quick change steelholder", MULTIFIX Size A, from Paulimot. Print 4 PCS, and you can store your unused steel on the backplate of the lathe. AMD. Sorry, i just saw that "Inthebay" have made a semilar design longtime ago. I did not know, and i have no intention to steel his briliant design.
