00:00We designed and 3D printed a seam allowance set in three sizes, 1, 1.5 and 2 centimetres.
00:08In the past, I used an ordinary stainless steel washer to trace a larger outline,
00:13for example when cutting foam for a plywood seat.
00:16But as you can see, this method is not very accurate and it can be awkward to use.
00:23That's why I designed these rings with a tapered opening.
00:26This allows you to use different types and thicknesses of writing tools, including pencils, pens and markers.
00:34Simply place the ring around your template and follow the edge to draw a larger outline at a consistent distance.
00:40You can use the rings not only for cutting foam, but also for enlarging fabric templates.
00:47The STL files are available to download for free.
