This is the Y gantry bottom parts for the VzBoT Vz330 used to replace X gantry to lower cost, lighter weight 1515 size instead of 2020 size.

The geometry and shape is based on the Vz330 V1.2's Y gantry except for minor differences and is fully compatible.

note: After the Vz330 V1.2 is released, the left and the right of the Y gantry are not common parts.  If you are using less than V1.2, please re-printing and combining Y-gantry-top-left and Y-gantry-top-right released by official VzBoT.

note: The standard inner width is 15.2 however please try to use 15.1 or 15.0 instead of 15.2 if your fitting is too loose. For my VzBoT I used 15.2 but use 15.0 now to use CF-ABS that is low shrinkage instead of standard ABS.
