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

  • Image Added
  • Image Added

  • 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

Expand

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?

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 (thinking of sticking with this option)

  • 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

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

  • brushing on to the 3D print

  • easy procedure

3D Gloop

  • brushing on to the 3D print

  • easy procedure
