Weld tabs

where to get them:

Industrial Metal Supply Co. – https://www.industrialmetalsupply.com/Products/welding-tabs#1

• 6 types of style

McMaster-Carr. – https://www.mcmaster.com/weld-tabs/

• lots of variety and provide 3D model and technical drawings of the tabs

• greyish- warm/soft white

• attach of fabric (grey or it could be coloured)

  • according to Google fabric materials are:

    • Fabric: 33% nylon, 67% polyester

    • Hydrophobic and antimicrobial coating – should be able to prevent the fabric getting dirty

    • Polycarbonate (hard plastic)

• could add colour to fibreglass / or colour it afterward

  • if we are sticking with google home aesthetic, just need to make sure that it looks like the white colour they use

  • Open

    

    maybe the first 3 colours? white colour with a tint of grey/beige

    • #F7F6F0, #F5F6EC, #F6F5ED

  • Open

    

    this colour was used in google store #F8F8F8 in hex ( I think this is the colour… )

  •  

  • google home has a dim 4 colour light on the top… should we consider that part?

Sticker on Latches

• 6 latches on the battery cover

  • since the cover can be opened up after all 6 latches are unscrewed, might be possible to have only one sticker/label on one latch (not necessary to have a sticker on all latches)

How to put sticker

•  

• put a vinyl sticker on top of the latch so that it covers the screw

  • must be peeled off to gain access to the battery cover

  • putting one sticker on the bottom latch of the battery cover

• sticker can be written like this:

  • Do Not Open The Cover

Latch is 31mm wide, so thinking of 50mm sticker or even bigger if we want to put wording

These are some ideas for the sticker:

The sticker can be made by putting a huge tape over the printed paper label (kind of like a library sticker).

Or if we want a professional sticker, could just print the wording/logo on to the blank sticker page (not thinking of this option because companies don’t sell one single sticker)

• problem: fabric

  • if we decide to attach the fabric all on the cover, the sticker might not stick well

  • maybe have to glue it with “easy peel off” glue

Marking

• top of each cover must be marked with letters at least 10mm high with

  • “Caution: Chemical Hazard”

  • “High Voltage”

  • type of the battery (ex. Li-ion)

  • any other standard hazard marking specific to the type of battery as well

• Where to put:

  • one on each cover

    • assuming that it is one on the battery cover and one on rear electronics

Embroidering

• works almost on any fabric

  • cotton, wool, linen or silk – anything to be honest

  • would really depend on what fabric we choose to do

    • especially on tightly woven fabrics

    • Woven Fabric

       

    • nylon fabric

      • works for cars typically

      • not cotton (for right now)

         

Style:

• Wish if it is embroidered with MS style

  • Roboto font, MS colour (yellow and blue)

    • might change depending on the fabric colour

    • ex. if the fabric colour is darker than what I expect, then the font would be white

How to?

• could make a sticker and stick it on to the cover

• or actually mark it to the cover itself

How to make 3D printing less 3D printed looking

• key point is: how can we smoothen out the surface?

• material: PETG
