Paper Sketch to Prototype: 3D Printed Knob

Recently I designed a low-cost electronic knob using Texas Instruments inductive sensing IC, LDC1312. For the Mechanical part of it I used ProtoDnD and got help from a 3D designer to convert my idea into a 3D model. Here is how a paper sketch was converted to a 3D model and 3D printed.

ProtoDnD is a platform to get 3D Models made from real designers. Its very cheap to get a 3D model made, I paid $30 for this project.

Upload any relevant images/docs/description which you can share with a designer to get started on the design. You can also annotate images that you upload to be clear and specifc about your 3D model requirements.

Once the quote is accepted, designer starts working on your project. You can also send a message or share images or other documents with designer in your project dashboard on ProtoDnD.

ProtoDnD also has tools to annotate STL to specify a feature modification in 3D.

Payment is released to designer when the design is accepted as final.

This model was 3D printed on MakerBot.
