Stock vacuum cleaner have saveral issues:

• Sucking hole is too big - due tu a laws of physic bigger hole gives lower speed and suction power. So if no tube accessory used - suction power is very weak.
  Another issue there is no where to put accessories when you wan to cary vacuum cleaner with you. So I made longer cap and shorter version of the tube. Of course sometimes you need longer tube. This mod kind of trade-off. Now I can cary all needed accessories together with vacuum cleaner (brush, tube, cap).

Different filament may give slight size difference by 0.2-0.4 mm. If so try to resize the model.
