This is an improved version of the print-in-place dispenser for lickable treats for cats. It reduces the messines of using such treats and allows to retrieve every last drop from the tube.

Improvements over the original model:

• relaxed tolerances for easier movement of parts;
• latching mechanism to close the dispenser;
• guiderails for the sliding part for slicker movement;
• sturdier build with increased wall thickness.

The model was tested by printing in PETG using 0.4 mm nozzle with 0.2 mm layer height.  For a 256x256 mm bed, the model needs to be rotated by 45°. No supports are needed.

Make sure there are no seams adjacent to the sliding part. To enable movement of the sliding part, twist is with a reasonable amount of force applied.

Make sure the chosen filament is food safe. Food safe PETG is a good choice that allows cleaning the dispenser with hot water. Make sure to clean the dispenser thoroughly and replace as needed.

UPDATE: The interface between the shells was adjusted to make sure the device remains closed.
