Pet Tracker or Wearable

I am looking for a solid model of an engagement ring. I know what I want, but I need someone to model it for me so it can be cast

I want a design for a device that will rotate a wheel about 10 inches in outer diameter about 1 complete rotation back and forth. I prefer for the device to sit on the floor and rotate the wheel back and forth instead of attaching to the carriage frame since I don’t have any carriage specs and they may vary depending on which model is being used The device could attach to the wheel itself, rim or tire. It should be adjustable though to fit on a few different size wheels. It should be designed to be able to adjust to a wheel from 7 - 10 inches.

This is to be a prototype device so it may have a few iterations. There will be additional funds for a planned phase II of this prototype. The idea is a way to secure cordage or twine. The rough specs are 40mm long, 20mm wide and 5mm thick at the base. The cam should be modeled similarly to the look of something you would see on a sailboat. The arch must be just slightly lower than the top of the cam. The cam should be usable for 2mm-6mm cordage.

Hi I am after a design of a pendant which will be gold and whole design should be raised from the base I have provided a image of a similar outcome of the technique used of raising the border and actual design which I want implemented in the new design The plug on the design should be 3 dimensional on a side perspective with the 3 pins someone how raised and the word "the" should be paved with diamonds small enough to fit 2 rows throughout

I need a 3d design. Think of a signboard like this: http://theavtimes.com/wp-content/uploads/2013/07/Rave-Party-cancelled.jpg And now we need it smaller and more fashionable. So that someone can hold it like this: https://s-media-cache-ak0.pinimg.com/236x/54/44/a7/5444a7e33dc23f718172ae176a5effca.jpg http://cdn.acidcow.com/pics/20101217/smart_and_creative_31.jpg The pole should be one that can be expanded with the push of a button. The pole will go up to a max of 12 feet. And when no expanded it will be 6 feet. The pole should have 3 buttons on it. 1 button will increase the height of the pole, the 2nd button will decrease the height of the pole. And the 3rd button should lower a stand so that the user can set the sign board down and not have to hold it. Look at this youtube video: https://www.youtube.com/watch?v=85R0_2QGunE You see how the button makes the umbrella open and then close. I want the same the thing. if the person click the button then pole will extend and if they click it again it will go back down Oh also can you make it look kinda futuristic. Do you know what a lightsaber is?

I want the plastic with the light inside. So it glows. So that it will be strong on the inside, and then on the outside there will be a glowing light to make it look cool On top of the signboard will be a cheap lcd screen. This screen will display text or an image on it. The pole shouldn't be too heavy but it should be strong enough to securely hold the lcd screen on top. The wires should run inside the pole and nothing should be shown outside. I am attaching an image of something really basic but similar to what I am looking for.
