Hello,
I am designing a clock at the moment and the idea for the casing is to sandwich two PCBs stacked on top of each other between a flat piece of perspex and also a bent piece at an angle.
I have attempted to draw my idea using characters above. The green is for PCBs and the black is 3mm perspex.
So my question is, how to I know what length to make the base? And also what angle it needs to be at?
Currently the longest "upright" section is about 6 inches and the base is about 3" and the upright is at 70% from the base.
I haven't got the parts made yet, so I don't have any way of weighing them, but they shouldn't be too heavy. What I don't want is to manufacture the parts to find it either falls forward and won't stand up or it topples back.
I will be laser cutting the perspex to get a nice clean cut and smooth finished surface, then using a strip heater to make the bend. Ideally I don't want to have to heat the bend more than once, because it will look messy. Once an angle has been established, I can make a simple bending jig to fold the plastic around.
Any guestimations or ideas/theory would be most appreciated.
