This is not my design / model. The original model by Hank can be found at https://www.printables.com/model/55159-large-mantis-clamp. I am sharing this here under the CC BY-NC-SA 4.0 DEED license for easy printing on bambu printers. No changes were made to the model itself, but changes were made using print profile settings (see below).
The model is designed with a 0.2mm clearance on the gears. I added a second print profile with a 0.1mm X-Y contour compensation to make the clearance just 0.1mm. This results in a very tight fit with almost no slop in the gears with tightening the clamp.
