Improved Endcap for Dyson DC 44 Animal

thingiverse

Oh my lovely wife, I showed her how to clean the brush bar of our DC 44 Animal, but she ended up taking a pair of scissors to the "coin screw" slot instead, which basically ruined it. So I had to design a new part because it was ridiculous that we needed to find a coin to open the brush bar every time. I seized this opportunity to improve the design slightly by adding a lever to hand-open the part. Problem solved! In the end cap, I intentionally left very little tolerance on the brass bushing part, but what works well is heat-setting the brass part when assembling it - just turn it a bit and it will allow the round part to still rotate slightly.
