This is the perfect kit for upgrading tt01. Rigidity will increase and weight will decrease effectively. Also this kit makes your tt01 more beautiful :)
Kit designed with clever small details but there is one negative detail which is about the motor mount. Pinion and spur gear can not easily touch with each other even screw is in the end of the setup rail. There is no information how to do it in the manual sheet. Screw type changing can be the solution for that.
