Unger Broom Handle

This is a clone of the Unger broom handle. It has both the locking and plain threaded design. Unger brooms are commonly found at big box DIY stores like Home Depot and Lowes. My handle broke after falling over from an upright position only TWICE so I pulled out the calipers and made my own! The tolerances are a little tight on the locking end and the tabs will dent a bit after being secured once but it will still unlock and lock properly. Overall length is a few mm longer than the stock handle but overall a very close clone.

It prints WITHOUT SUPPORT as long as you print it plain side down (locking side up, hanging hole away from the plate). I suggest a brim as contact area is thin. 

Test prints were done in Zyltech Matte Black ABS (don't use matte ABS. Matte filaments are weak and I would not recommend them for this. I broke 2 matte ABS handles drop testing them) and Bambu ABS. With only the default 2 walls, the handles will probably break where it screws onto the broom shaft. That's where mine both broke regardless of what I did with the matte ABS. 30% infill is probably overkill but I wanted to make sure that it didn't break. I didn't test PLA since I often leave my broom outside and ABS handles impacts better.
