This model is designed to repair a sprayer with a broken neck, specifically when the break occurs just above the cap.

Printing Instructions:

Print the left insert, right insert, and the cover.
First, slide the cover on with the slot openings facing down.
Install the inserts, aligning the notch over the yellow ring above the screw cap.
For the second insert, attach one side first, then roll it to meet the other side.
Slide the cover on top, aligning the slots, and apply a firm push if needed to secure it.

Use PETG for better chemical resistance compared to PLA. No supports are required.
