Measure the length, width, and height of your model with a ruler as the printed drawings are to scale and note them down in someway that will allow you to understand what you need to do and what is happening (Tools you need to use are on the left side). For some people who doesn't want to measure it out you can also just cut out your design and stick it onto the piece of wood you're working on.
Draw out the length and width on the piece of wood you are cutting out from. For the height if the wood isn't tall enough, cut out a shorter second piece.
Use the band facer to even out the surface of your wood block so that when you stick the two blocks of wood together there will be no gaps. For the smaller piece of wood I needed to use this tool so that I don't accidentally sand my fingers off (just being careful because it would be bad if that happened). Also when sanding the edges later on, read the sign above as I did kind of break the sand paper belt because I was sanding my wood the wrong way😅
In my case, once I've have gathered all the blocks of wood I need for my base, I used wood glue to stick them together and a popsicle stick to spread the glue.
Attempt #1 (It didn't stick together and fell apart)
Attempt #2 (Struggled to find the flat side)
Draw out your model's shape or cut out your model's shape from the A3 paper and stick it onto the wood. Bring the block of wood to the band saw to cut out the shape.
After roughly cutting out the shape of your model it will look sharp, unless that is how you want it to look, to make the surface and edges/sides smoother you'll need to use the band facer (a machine to speed up sanding things).
For an even smoother touch use a file and wet and dry sand papers. I used the file first, then the 320 grit sandpaper and then the 400 grit, increasing (the lower the number the rougher, the higher the number the smoother).
Final ↓
(forgot to take photos) For my resin design I needed to cut parts of my wood block into lots of pieces and then stick them back together with wood glue due to my complicated design.
In my circumstances, I needed to use tape
Put the plastic cup on a scale and set it to zero so that the it's not measuring the cup's weight
There are two parts of resin, Resin A and Resin B. To make the coat you need to pour in 20 grams of Resin A and 10 grams of Resin B. We do this so that there will be no air bubbles on the side (wood) when we pour the resin in.
Stir the two resin together for a while.
