Pipe Parts that monitor the depth of the water in your boat bait wells. This part was created by me because two of them cost $90.00 at the Marine Supply. These parts allow you to print your own for a few dollars. I printed my parts on a Bamboo X-1 Carbon 3d printer. The printer is a time saver and easy to use. It is a Professional Printer at prices that are very inexpensive for the professional 3d print market. I have purchased many different printers and this one beats all of them hands down. I am not in any way affiliated with Bamboo Printers. They did not pay me to advise a purchase from them.
