You can download the STL file in a zip file of the 3d drawing for the back button here for free. With the drawing or STL file you can go to a 3d print shop and have the back buttons printed. Do you have a 3d printer yourself? All the better, of course. What’s also nice, you can scale the button bigger or smaller yourself. This is a perfect solution for upholsterers who do not need so many buttons. You just have the exact number of what you need 3d printed. You use a back button for example of you are doing for a headboard or diamond tufting a chair. The great thing about this backbutton designed by us is that it has large openings. Then you don’t have to fuss to get your twine through the openings. Below a video how the back button works.
