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

Google Home Aesthetics

Expand

  • 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

      • 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?

Seal

Expand

What to include:

  • indicates contravention of the regulation --- ask lead what contravention would be

    • provisions (like regulations I believe) to seal battery/enclosure - be made by the team

      • o prevent unauthorized actions

“a seal will be placed to indicate contravention of this regulation”

  • to figure out if we accessed to the battery or not

Marking

Expand

  • 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

Style:

  • MS fonts – Roboto, colours

3D Printing

Expand

How to make 3D printing less 3D printed looking

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

Method

How-to

Pros

Cons

Sources

Sanding

  • will need different seams

  • after sanding, spray filler and spray paint can make the parts to look not like 3D printed

  • able adjust how smooth we want the surface to be

  • can be accurate in a way since we are sanding the parts that we want

  • could make a mistake of sanding to much

  • if it is a large part, time consuming to sand the whole part

Using Acetone

  • pour small amount of acetone into the glass that has paper towel in it

  • put the model inside the glass, and put a small fan in it so that the air moves

  • displace water around so acetone doesn’t leak

  • acetone will melt the 3D model

  • take it out, and dry the 3D model

  • acetone does its job to smooth our the surface

  • takes only about an hour

  • must be printed with ABS (Acrylonitrile Butadiene Styrene)

    • which gives toxic chemical when heated

    • shrinks when it is cold

      • not suitable

  • when doing this, could be dangerous since it is flammable

  • details can be gone

Using Spray paint / Spray Fast drying polyurethane

  • spray paint (more than usual) then spray a layer fast drying polyurethane, fan it

  • do this multiple times

  • no need to sand the 3D model

  • the details might be gone

https://www.youtube.com/watch?v=rn4edNztaPU

Shorter Layer height

  • set the layer height as a low number

  • no need to do an extra step of smoothing out the surface

  • time consuming

  • longer the time, easier for the machine to get jam and stuck

Heating

  • use a heat gun / hot air gun and along the surface of the 3D model

  • fast (I guess?)

  • able to choose parts to smooth it out

  • can change the shape entirely if it is too hot

Using brush on coating

  • brushing on to the 3D print

  • easy procedure

3D Gloop

  • brushing on to the 3D print

  • easy procedure

  • material: PETG

Ways to Attach Fabric

Expand

  • 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

Access Points

Expand

Access Points are:

  • power supply input

  • AUX battery input

  • USB ports for phone charging
