The Benchy Cali-Trailer

Works with Benchy and the E3D cart - https://www.printables.com/model/320875-e3d-cart-for-towing-the-benchy-and-cali-trailer

A simple little trailer for the benchy that focusses on calibration for unsupported overhangs, bridging, linear advance, and bed adhesion. It also includes a 0.2mm tolerance test if you're up for the challenge.

• Bridging - there are 5 bridges in the main body of the trailer of varying lengths.
• Overhangs - More challenging than the benchy as they quite thin.
• Linear advance - The sharp edges of the trailer are a good spot to identify issues with linear advance.
• Bed adhesion - Very small bed area for adhesion. 
• Tolerance test. The wheels can move separately and have 0.2mm clearance. However, they are very small so consider this a challenge, not a serious calibration.
