Adapter 1/4" Hex Shank sang 11/32" Hex Socket

Ever find yourself needing just the right adapter? I ran into that when I wanted to use a respooler I had previously 3D printed. That's why I designed this simple yet effective adapter: 1/4" (6.35 mm) hex shank to 11/32" (approximately 8.73 mm) hex socket.

For optimal strength, I printed it flat on its side using PETG, which aligns the layer lines with the rotational axis to minimize the risk of shearing under load. Supports were necessary during printing, specifically beneath the shaft and within the socket. These should be easily removable with tweezers for a clean finish.

This little adapter has been quite handy for my respooling needs. Hopefully, it can help you out too!
