I have setup a 6 steps method on how to make a desk tidy using a 3D printer and a sheet of polypropylene
To build this you will need:
A chisel (depending on the quality of the 3D printer)
A hand drill
A 3D printer
A computer (with autodesk inventor on it)
A Stanley knife
A USB
Polypropylene (about A3)
3 rubber dials with a diameter of 4 mm(optional)
Step 1: Designing the Frame
To make things easier I have uploaded a video on how to use Autocad for encase you are unfamiliar with it
I personally prefer to use Autodesk 2016
To download it go to 'https://www.autodesk.com/education/free-software/inventor-professional'
Ensure that the file you are making is in millimeters and not in inches
Firstly you would make the circle which is 75 mm and then make the legs which you can decide on how long and thick you want them but try not go any smaller than 10 mm
