4 round parts

5 squares

and 2 custom bolts

that i made

part is called Quick sketch.stl

Step 1: Step 1 Creating the Base

take 1 square and make it 80x130x8mm

then take the other square and make it 80x130x5

then take the last one and make it 5x5x130

then align them so it looks like this

Step 2: Step2: Creating the Hook

make 3 of the 4 cylinders into size 10x10x36

and the last cylinder will be hole piece and it will be 5x5x100

then align them so it looks like this

Image above

then group it

then allign it with the model

it should look like this

To make the supports you need to use 2 box parts and make them both 100x5x5 and angle it at 45 degres

you might have to use hole to cut away the excess on top then align them like this

The sccrews are optimal but i just took out 2 screws and put them like this

then you can group

thats it
