MacWork 3/8 & 1/2 Bộ Nối Dài Cần Xiết Lực

I got some breaker bars from aliexpress. The 1/2" drive was shorter than I expected (should have read specs more carefully) and the 3/8 drive was defective so I made this model to join the 2 handles together to give myself more options when turning those pesky seized bolts. I printed at 40% infill with 7 walls and it seems strong enough. The handles fit pretty snug. Also after printing I realized it could really use some fillet on the edges. I added that to the model but didn't bother reprinting. 

Hope it's useful to someone.
Enjoy!
