thingiverse

You're looking for a versatile spacer that can fit into various profiles, such as 20x20 and 20x40. This splicer has a threaded hole to secure it in place using a T-nut, making it a convenient choice. The attachment files are interchangeable, allowing you to choose the one that suits your needs best. However, you'll need to cut an M8 computer bolt to size for use with this splicer.
