The existing printer openings on DPD parcel robots, that direct the printed paper downwards, were originally designed poorly. The printed paper did not always come out and got stuck behind the inner edge causing jams. A new opening was designed based on the original model, where the exit transition was made smoother.

Before where there is a sharp transition edge and a large gap with the printer opening
After remodel, where there is better contact with the printer opening and a smooth transition

To improve the weather and UV resistance of the plastic part, the part was made of 3D-printed PETG material.
