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

  • 

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

    • #F7F6F0, #F5F6EC, #F6F5ED

  • 

    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

      

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

Ways to attach Fabric

• 3M Marine Adhesive Sealant 4200 Fast Cure

  • a way to attach fabric on boats

• contact cement

  • extremely strong chemical, might be to extreme

• industrial velcro

• any fabric glue

• could even make a small gap on the cover and insert the corners of the fabric

  • must figure out where we want to put fabric

Fabric Glue

Padding under the fabric

• could use a sponge foam role

• something like foam floor tile

Keeping the fabric clean

• could use hydrophobic and antimicrobial coating like how Google uses it for google homes

• the cloth of the car seat can be protected by the fabric protecter – we could use this to the fabric on the cover
  

  

Foam

• got some information from Sheila

  • open cell vs closed cell

    • closed cell has cells that are sealed off, therefore the air is not trapped

    • her guess is that we would want to use a closed cell that is firm/extra firm (closed cell is usually firm)

• Lux HQ foam / Neoprene Foam

• the website sells adhesive for the foam – looking in depth to this

Access Points are:

• power supply input

• AUX battery input

• USB ports for phone charging

Labeling and Making it professional

• could label with words and image

• engraving can work

ex.
