Extend Suction Cups Application with Custom Brackets. I Made them at TechShop.
The suction cups are a highly useful idea and solved a big problem. But when you involve a highly specialized tool that the majority of people don't have it limits the usefulness of the solution. Still... big thanks for the suction cup idea, I can jury rig something from there.
Actually, you have real CAD software at TechShop. Why fight with CorelDraw when you need exact dimensions?And I 100% I agree with lime3D. The laser cutter will cut all your vector cuts directly on your lines. In order to create this part correctly, you need to first create some test cuts in your material of choice. Then use a feeler gauge to measure the exact kerf (width) of the cut (which may also be affected by the power and speed settings, so be sure to record them). Then using a real CAD program like AutoCAD or Inventor (you have both at TechShop) create your drawing with real dimensions. Then offset the lines by 50% of the thickness you measured with the gauge.Save your CAD drawing as a DXF and bring it into CorelDraw or Adobe Illustrator for cutting on the laser.
Don't bother 3D printing this. The accuracy of your printer will not be good enough. There is no point in printing a measuring tool unless it can be perfect.
Way too much work for minimal payoff. Just 3D print a holder for a cheap laser pointer, and put it in the ShopBot chuck.

Yes. Nowadays, camera resolution are so high, you could zoom directly to small object placed under it. For microscope, you would need strong light downward or strong ambient light... depending on the object in question. I like to view insects close up with it. Thank you for your valuable suggestion.
I think if I put it in pdf format, you might be able to print it to exact scale. Let me think if I could help make a design that does not require laser cutter or 3D printing. I will update and reply here again.
Thank you. I like it.
3D Printing Class
Thank you. You could 3D print the top cradle and 4 brackets that connect the legs to the cradle and base. The brackets could be permanently glued to the base and cradle. The legs and base could still be made of cheap plywood and stained. The legs could be just rectangular and narrower. For the brackets, note there is slope angle. We could design one bracket and make 4 parts. If you need help creating the brackets drawing, I could make them for you using Autodesk Inventor. I could share both Inventor and STL file.
Another desirable feature of this design is that the parts could be disassembled and transport flat. I will made another version with a narrower base so that it could fit USPS Priority Flat Rate envelope. If you know someone who has access to laser cutter, the part could be cut and shipped to you.
Thank you for your comment.Since the legs are offset to rear side, the LED holes (for the legs) need to be close to the front edge of the legs (not in the middle of the leg). I think about 1/2 way vertically. One easiest way is an LED taped to CR2032 hack. http://www.instructables.com/id/LED-Throwies/.Use velcro or masking tape and tape the "Throwies" along the leg downward and directed to the center (along fore-aft direction). You could play with the optimum placement.

Now I want a laser cutter. I might 3D print out though. Great Job
