This model is not for printing but it can be useful if you are going to invent some improvements for your printer. Such as layer cooling system, BL-Touch mount, air ducts, etc.
This accurate, precise and high detail model was recreated from the scratch and presented in e3Dv6 configuration. Unlike genuine one, this version equipped with common e3Dv6 parts: heat sink (identical outside but has shorter threaded channel inside), 26mm throat with heat brake (instead straight 30mm throat in stock version), heat block and short "prusa-like" nozzle with thermal insulation/dust cover.
These differences are not so significant, but this combination has smaller overall length. So it might be important in some cases. Use this model for prototyping in case you have replaced stock Tevo tool head by common e3Dv6 parts.
