Knock Box Bar Remix

I have a very nice Knock box...to which I recognize the talents of Mr. DonJorhe. It is the perfect size and the styling is very nice.

I saw that if I was a bit overzealous with my knocking...I worried that I might dislodge the bar from one end or the other. So, I decided to see if I could remix the Bar...to put ends on it...so I need not worry about the bar sliding out of it's place ---( I should add...the bar never did slide out of it's place when I used it...so this may be a totally unfounded concern.)

This REMIX is in 3 parts. Two outer knobs...and the main bar. It's designed to be printed in ABS, and the knob without threads...to be welded to the flat end of the bar with acetone. Once welded together...the threaded end can be inserted into the Knock box...and the other knob screwed on gently. It should erase any fear of the bar coming dislodged, whilst maintaining the ability to disassemble for cleaning or bar replacement, should it eventually require that from use.
