I don't have a 3d printer to print this on. You can print it if you want just let me know. Please give me credit if you decide to share it. No selling it. If you do print it please send me photos and a video of it so I can see if it works. You need 2 1 inch diameter rubber rings for a seal around the pistons. It is made for a 12 inch by 12 inch board. You can scale it down but I don't recommend it. it wouldn't work anymore.
