Got the idea from on on here. Will get the url and update later. Made this real thin for quick printing and low plastic use. I may increase the thickness and upload it later. It printed o.k. but i think you would have to paint it to make it true water tight. I was going to paint mine any ways so didn't make any difference. Find you a cork to plug the top. I will get to the hardware store and find the right size to get for it and update then. The base fit great on mine, yet you may have to put a hair dryer on it and squeeze in the tabs a bit to make a good tight fit. Drop you a small piece of cantaloupe, water-melon or maybe a few pinches of banana and stand back and watch the fun. You can even string a twine thru the cork and hang it up somewhere. I may try that myself. Enjoy, Rick. UpDate: For fun, I just made me a plastic Cork! Works fine for setting on my desk. Don't think they can push it off and get gone! :)
