These are Scroll Saw Mount Inserts the blade passes through. They have been 3D printed. The outer diameter is 2.947 inch or 75.0 mm diameter at the top. Inside diameter is 63.5 mm. Thetop flangethickness is 3.0 mm, the second supporting ribs are 3.0 mm. The insert was made from an original insert for a DREMEL 1800 scroll saw to replace the one that came with the saw.These inserts are new and have been tested for fit.
The PLA plastic is soft enough not to damage the blade if it contacts it. They come in a pair of red color inserts so you can have a spare at a reasonable price. Theseinserts have three legs that extend into the table socket and a post that fits in a hole made to keep it from turning while in use.
If you have a saw insert with different dimensions, contact me and I'm sure with good measurements and some photos, Ben's Creations can make one for your saw or application for you.
