Shark Crevice Tool Mk.4

thingiverse

I designed a crevice tool for a Shark Navigator Professional Lift Away vacuum cleaner using Onshape. You're welcome to adapt this design as you see fit. ***4TH ITERATION*** I'm genuinely fond of fillets, I must admit. ***3RD ITERATION*** Why do I keep creating these tools? Okay, well, this one was necessary, but I'm done for good. No more after this. I had to flip the catch around in Mk.2 because it was angled backwards. I also added a bit more tolerance so I wouldn't have to sand the final product as much. Additionally, I defined the size and position of the rectangular end relative to the attachment instead of just eyeballing it like I did previously. ***2ND ITERATION*** I've added clearance to make for a better fit with less post work. I've also included features that improve airflow and reduce turbulence inside the tool near the attachment point. This should result in a small but noticeable improvement in suction due to reduced energy loss to turbulence and dirt buildup inside the tool. https://cad.onshape.com/documents/c0098c74fabf15220efffcbb/w/ab17b34ab6d89a53e4131dc7/e/ac5487adc4c36c86f423cd54
