Shark Stratos - IZ400UK - IZ400UKT - 32mm adapter

This adapter will allow you to connect generic 32mm vaccum attachments to your Shark Stratos IZ400UKT vaccum. It closely follows the design of the original Shark adapters, and although it's not a perfect fit (it's more difficult than it looks to design, and perhaps a lack of skill on my part), it seems to be mostly air-tight and shout fit your needs without having to purchase expensive new attachments and have the ability to 3D print your own attachments for your vaccum.

Hardware required:

• Compression spring around 80mm tall with an inner diameter of roughly 5.5mm and OD of around 7mm (I used a spring out of a spring pack I got on Aliexpress)
  • Note: If you can't find the required spring, just change the size of the spring notch in Tinkercad, it's simply there to keep it roughly in place
• 30mm M3 bolt (and nut, but isn't really needed)
• A Shark vaccum, of course!

Print reccomendations:

I've included a 3MF file with my print reccomendations already embedded, supports already set up and prints oriented in the correct direction, but I'll also include them here for completeness.

• I would reccomend to use PLA - PETG is a little bit “sticky”, but chances are it'd work if it's all you have

Body:

• 15% infill (choose your infill, doesn't really matter too much - if you're not sure stick with the default your slicer offers)
• Tree supports, supporting:
  • Inside the hole (underneath the model)
  • The bottom outside of the latch on the main body
  • The top inside of the latch on the main body
  • No other supports are required - do not use normal supports, you'll struggle to remove them

Latch:

• 4 walls
• 100% infill
• Print the latch flat face down, no supports needed

Assembly instructions:

Make sure you've removed all the supports, don't forget the ones on the underside of the model, and you're ready to assemble!

1. Place the compression spring over the retaining notch on the main body - this should keep it in place
2. Place the latch inside the fitting hole in the main body, and line up the screw holes
3. Screw in your M3 bolt - this can be a bit fidgety to get everything to align but eventually it will go through the other side

You might note that the latch inside pulls towards the opposite side you screwed your nut in to, this shouldn't impact the functionality, but if you're OCD, lightly unscrew the bolt a few turns while also pushing the latch in the way you need it to go to even it out. You'll get it roughly in the centre. The reason for this is the tolorences are quite large due to this being quite a complex part not to design per-se, but to actually get to fit properly on to the vaccum.

Future notes:

• Currently only 32mm attachments are supported, and there is no tolorence, so when printing your fittings, you might want to scale them down slightly. I'll release a fix for this in the future and add a bit of tolorence once I've had a chance to test some of the printable attachments.
• I'm aware 32mm isn't the only size attachment out there, I plan to update this in the future to allow for a larger range of sizes to be accepted by this adapter - if you need a specific size, leave a comment and I'll know where to focus my energy.

Thanks:

• I originally bought https://cults3d.com/en/3d-model/tool/shark-cordless-vacuum-cleaner-adapter-for-iz200-iz250-iz300-iz400 as it said it supported the iz400, turns out it actually didn't, Shark decided to flip everything round. Despite that, the inspiration for me creating this model comes in part from the author “MART_EM”, so I want to thank him for his contributions to the 3d printing community.
