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
- this colour was used in google store #F8F8F8 in hex

What to include:

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
indicates contravention of the regulation
- provisions (like regulations I believe) to seal battery/enclosure - be made by the team
- to prevent unauthorized actions

How to make 3D printing less 3D printed looking

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	https://www.youtube.com/watch?time_continue=258&v=NLoB52nPuao&feature=emb_logo https://www.youtube.com/watch?v=0vgynnYzo08
Using Acetone		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	https://www.youtube.com/watch?v=6xFUNFG-UKE https://www.youtube.com/watch?v=rn4edNztaPU
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 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
