Sketch drawing to CAD/.stl file

This is a file of a die that is just too large for some reason. I want to make a mold of dice 10 dice wide and 10 dice tall which would get me 100 dice. I want to pour food grade silicone around it and then use my mold to pour candy dice. I need someone to redraw this die.igs file so that I can get a 3D print mold out of it. Prob save as .igs or dxf

childrens playground, just a simple base with 3 activities, a slide off of one side, a tunnel slide off the other, and a pole with two swings off the other.

Hello, I have attached a blender file that has two objects in the file. The intention of this project is to create an enclosure for a robot. The circular object is the base which will go on top of the robot, the chassis is this (mm), I believe i have already adjusted the initial enclosure to fit on top of the chassis but please verify. http://image.dfrobot.com/image/data/DFR0310/Upper%20plate%20V1_Layerout.pdf I would like the chute object to be mounted on top of the enclosure, where a marble will sit in the chute and when the robot spins, the marble will slide down the chute.

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.
