Model origin
The author remixed this model.
Differences of the remix compared to the original
The original model (which is different from the pictures in the original model listing so I assume is a mistake) I referenced had some flaws which I have fixed to fit my CNC. Please check your measurements before printing!
1. I adjusted the model so there's a space for the anti-backlash T-nut.
2. I adjusted the size of the Z-axis leadscrew heat insert nut to fit the nut on my machine (~12mm OD).
3. I adjusted the distance between the linear bearings to be 38mm on center apart (original model was 40mm on center leading to slight fitment issues).
