Popcorn Coffee Roaster mod

So like most people I enjoy a good cup of coffee. I have been brewing my own espresso for awhile now and discovered that store bought beans kinda suck. I found myself a local roaster and found that freshly roasted coffee beans are the way to go. Unfortunately going to a local roaster is expensive or not even an option for some people. I did some research and found that a lot of people were roasting beans in a popcorn machine with good results. I went out and bought my own and tried it. To my surprise, the roast came out extremely well. Unfortunately, It made a huge mess. the chaff blew everywhere and half of the beans blew out the popcorn opening. definitely not ideal. That is where this mod comes in. You slide the smaller cylinder in the popcorn chamber to keep the beans from flying out. the larger cylinder slide over the first to collect all the chaff. this is all a work in progress and you might have to adjust the size to make it fit your popcorn machine. This is still a work in progress so let me know if you have questions or suggestions.

-update, dont use PLA it cant withstand the heat.
