Design & Make - Emergency Candle Holder
MYP Design Orientation Skill Building Challenge
A culture of emphasis on workplace safety and well-developed technical skills allows for student agency in design projects.
Design Specification
Fitting - The parts of the holder fit together very well with no gaps.
Fitting - The tealight and the matchbox fit snuggly into the holder.
Aesthetics - There are no glue stains and the holder has a smooth sanded finish (surface and edges).
Safety - The holder is flame retardant.
Sustainability - The candle holder needs to be efficiently made from a single piece of 15mm plywood of 100*150mm.
Modelling - Make a foamcore model of the
Station 1 - Mark out model
Watch the video carefully
Complete the Utility Knife safety quiz on Quizziz.
Mark out and cut your foam core model pieces. Cut the hole for the candle first. This will give your fingers more grip on the material. Dimensions can be deduced from the pictures and design specifications above.
Station 2 - Assemble model
Watch the video carefully.
Complete the Hot Melt Glue Gun safety quiz on Quizziz.
Assemble your foam core model following the instructions in the video. Note that there is dowel in the assembly.
Annotate your model with dimensions and other notes that might be helpful when creating the candle holder .
Creating Parts
Station 3 - Marking out main parts
Watch the video carefully
Mark out the parts of your candle holder on your piece of plywood following the instructions in the video.
Station 4 - Cut tea light hole
Cut the large holes for the tea light holder using a 40mm Forstner bit on the drill press.
Station 5 - Cut plant holder main parts
Watch the video carefully
Complete the Band Saw safety quiz on Quizziz.
Cut the three main plywood parts on the band saw.
Assembly
Station 6 - Cut dowel joint holes
Watch the video carefully
Complete the Pedestal Drill safety quiz on Quizziz.
Drill the holes for the dowel joints using the drill press. Make sure your job is properly secured in the jig!
Station 7 - Glue and clamp
Watch the video carefully
Glue the pieces together
Install the dowel
Remove excess glue with a wet rag
Clamp your candle holder
Make sure your clamped candle holder is labelled with your name and class and stored where your teacher tells you.
The glue needs to cure 2 hours under pressure and another 24 to fully bond.
Finishing
Station 8 - Sand Flush
Watch the video carefully
Complete the Disc Sander safety quiz on Quizziz.
Sand your candle holder on the belt or disc sander to make sure they are the correct length and the edges are square (90 degrees).
Remove the excess dowel.
Station 9 - Sand by hand
Watch the video carefully
Sand your candle holder by hand using a sanding block and sandpaper.
Clean away any sawdust
Station 10 - Oil
Watch the video carefully
Varnish your candle holder fire retardant water-based PVC varnish
Make sure your varnished candle holder is stored where your teacher tells you.
Tip: Store your just varnished product on two pieces of dowel for minimal touching of the ground surface.
Planning
Develop a technical drawing of final product. You can choose between
Five orthographic projections. OR
An isometric projection. OR
Extension: isometric exploded view
Whichever you choose, your drawing must have:
Dimensions in mm of all parts of the candle holder without duplications.
Basic rendering with Copic markers (do this before tracing with a black pen!).
Crisp lines with a ruler.
Be fully traced with a black or blue pen (including dimensions).
If you choose orthographic projections, ensure you:
Use a 1:1 scale. That is: 1 unit in your drawing corresponds to 1 units in real life. E.g. 40mm in your drawing would be 40mm in real life.
Accurately and logically align all views.
If you choose an isometric projection, ensure you:
Use a 1:1 scale. That is: 1 unit in your drawing corresponds to 1 unit in real life. E.g. 40mm in your drawing would be 40mm in real life.
Add all major dimensions. Make smart use of the isometric grid to do so. See the example below.
Use correct line weights.
Use triple shading - Top once, front twice, left thrice

Tips
Make one or more sketches of your drawing on scrap paper first.
Draw your final drawing thinly in pencil first. Then add colour. Trace it with a pen last.
Common mistakes in orthographic projection drawings:
Projections not aligned,
Projections too close to each other
Projections not at the same distance
Dimensions on top of a projection
Dimensions too close to drawing
Dimensions repeated unnecessarily
Dimensions not properly stacked
Dimensions in between projections
Dimensions with units (units are not needed)
Common mistakes in isometric projection drawings
Dimensions on top of a projection
Dimensions too close to drawing
Dimensions repeated unnecessarily
Dimensions not properly stacked
Dimensions with units (units are not needed)
Common mistakes shading with Copic (alcohol-based) markers
Choosing a marker with a hue that is too dark.
Not using some scrap paper under your drawing.
Using Copic markers after tracing with a pen. Colour first. Trace after.
Everything, including dimensions and the legend in the bottom right corner, needs to be traced with pen.
Extensions and put to use
Extension 1 (optional)
Model your candle light holder in Onshape and create a digital technical drawing.
Extension 2 (optional)
Create an engraving on the top in Adobe Illustrator and have it laser engraved.
Put to use
Write a thank you note to your parents or caregiver that has been important to you to start this academic year well.
Give your candle holder, with a matchbox, tealight and a great smile on your face to the person you are grateful to!
2. Drilling the hole for the tealight
Prepare
Pass the pillar drill training Quizziz.
Ask you teacher whether you have marked out your work correctly.
Do
Remember what you learned about pillar drill safety
Clamp your work securely in the flat vice.
Set the depth stop at an appropriate height.
Drill with some force. Larger chips should be flying off.
Consider
3. Cutting the main parts
Prepare
Pass the bandsaw training Quizziz.
Ask you teacher whether you have marked out your work correctly.
Do
Remember what you learned about bandsaw safety
Set the bandsaw guard at an appropriate height.
Cut slowly but steadily. Use a push stick if your fingers come too close to the blade.
