Keep the dimensions of the box exactly as they are in the 2D version (they are in imperial but can be changed to metric in the solidworks file) I'm looking for a clean 3D Solidworks file of the exterior with the 2 cords that can pull out almost to look like an assembly drawing in Solidworks. I'm not looking to get detailed on what the product is or how it will work, but the top port is a Micro USB, and the bottom port is a Lightning USB. The notches on both are for fingernails and a cord will pull out. There is a very small power button on the bottom and 4 LED lights on the back side that I will update soon. I'm looking for conceptual nice looking design to use for sale of the product.

3D modeling of a J-shaped massage tool, much like a Theracane only smaller in dimensions. The tool should be modeled as close as possible to the attached images. The straight portion of the J-shape is approximately 10 inches long and 3/8in in diameter. The hook portion of the tool should form an approximately 180 degree arc and terminate in spherical end of 9/16in diameter. The handle, at the top of the J-shape, should be approximately 3/4in in diameter. The attached jpg images are of the actual tool that I would like modeled and should give you a good idea of it's dimensions. The png file should also provide a good reference. Thanks.

Hi, We need a waterproof air monitor for our drones, which has enough airflow to detect particulates, gasses and other pollutants. And has no water ingress. The enclosure needs to be made from plasics, ABS of PLA, and there has to be an atenna for a LoRa module an arduino and batteries. The sensors will be placed directly onto the arduino.

The spiral of learning (Kolb & Kolb) is a simple helix visualising the learner's progress. I need to visualise a more complex spiral. Turns on this helix are circular. Each turn represents an interaction between teacher and learner. This helix contains 1 grand turn. A grand turn contains at least 3 smaller turns. This creates a turn complex. Each turn achieves a small or large rise on the z axis depending on the diameter of the turns on the x and y axes. In elevation view the turn complex should have a stepped appearance due to the presence of the smaller turns, with the lowest steps at left and the highest at right. The idea to be communicated is that the larger turns contain at least 3-5 smaller turns. Each turn achieves a small increase in z-height as the learner exits the turn, like freeway traffic using a cloverleaf junction. Multiple interactive turns aggregate to a large gain in z-height. In the attached illustration, the largest loop should be understood as not a part of the visualisation. I would like to see two variations of the design: (1) smaller turns ranged on outside of grand turn diameter (2) smaller turns ranged on inside of grand turn diameter.
