Unique Pneumatic Lubricator Demo Prototype

I am seeking the services of a qualified and experienced freelancer to help develop a unique pneumatic lubricator demo prototype. This prototype should showcase the functionality of the unique pneumatic lubricator. Though I am open to suggestions, I do have specific preferences for the materials that should be used, as well as the desired size of the prototype, which should be medium-sized (requiring a table or stand). This prototype should be a viable demonstration model that can be used to demonstrate the features, capabilities, and potential of the unique pneumatic lubricator. Those who are interested in this project should be highly proficient in their fields, with experience in creating and executing projects of similar complexity. This work should be completed in a timely manner, while also being of the highest quality.
