Sketch drawing to CAD/.stl file

Looking for a proprietary design for a 3D printed Cylinder Maze that nests together in 3 different “maze inside a maze” cylinders that fit inside each other. Similar design to: https://youtu.be/BHRYeOqLM9I

I am making some molds to be used to make pendants and Pyramids cast in resin. I attached the examples drawn to the best of my abilty hopefully you can see it in 3d. Pretty simle actually

I need someone to make a certain part of my 3D anchor stl file a little thicker. Nothing complicated at all! The guy that was working on this file is really swamped with work and cannot complete this edit. This job should literally take less than 30 minutes if you know what you are doing. On the attached picture it shows that I need to make specific parts of the anchor a little thicker to meet the minimum supported wire thickness of .8mm. Here's what the email I recieved from shapeways said: "Here is why we cannot print your model: The minimum thickness for free/supporting wires > 1.0mm and supported wires > 0.8mm for this material. Please thicken the wires of the model." I have specified what needs to be done on the picture attached. Please message me if you need clarification. If you know what you are doing and have worked with stl. files and understand the thickness minimum that shapeways requires for 3d printing then this should be a no-brainer.

We would like to create a 3D model for mohs surgery showing the way layers of skin are removed to track out roots of skin cancer Here is a diagram that reviews the technique. https://goo.gl/images/Ly85Qz These different pieces will have a counter sunk hole so we can glue a small neo magnet and hold it together Attached you'll find a basic idea of what we want here.

We need a light bulb with thread on - for 3D printing. We are a thread cutting tool company, and for making a commercial we need a light bulb with threads all the way to the top.
