How to why add Joints/Fiittings to a piece?
I´m currently making a project for University and we have to make the insides and outsides of a piece at our choice.
I choose an electric screwdriver and now I need to make the joints to hold the electric components inside the screwdriver so they don´t just float in there. (Kinda like in the pictures) This includes motor, led, buttons, batteries etc.
The thing is I don´t know where to start, the pieces must have to be precise enough to fit the motor and make sure they dont slide of the inside, wich honestly, I dont know how to do that, I´ve searched youtube and other websites in search for information and found nothing similar, I really just want to know where to start.
Thank you

Use the rib tool.
You'll form ribs on the interior of the device, then cut away portions of the rib so it fits around the motor.
Also look online for images that show similar tools being taken apart for inspection or repair: https://s3files.core77.com/blog/images/lead_n_spotlight/632816_spotlight_65113_nzKdc4koO.png

The motor wants to move in six directions. And it will have to resist torque along one axis, and axial forces along another. The method used to position/hold/clamp the motor in place needs to take those force requirements into consideration.
A bit of warning too, the inside of a device often eats up 80% of the design time. The outside is what we see, but the inside with ribs, fillets, ducts... those take a long time to model correctly. So make sure the exterior is the desired shape before making any interior features.
