That defeats the object of your project. Your supposed to draw the plans yourself and then work out measurements.
Create a stand out of cardboard (can use a cereal box), using the measurements that you thought of and the plan that you created.
Then you can find any flaws or any mis-calculated measurements.
If you are stuck with a design, do some research, which is most likely part of your project anyway on current stands that have already been made.
Don't just find one, find several. Then using those, create your own, you can use the same measurements as them if you want, but don't use the same design.
I done Product Design at college and went into extreme detail, at the end of it I got an A grade for everything. Good luck, need any help just PM me.
