The Coaster-Lid.

It began it's life as a slab of acrylic. Using a 3-axis CNC mill, it was machined into the perfect piece for office desktops. Use it as a coaster to keep rings off of desks and utilize the spoon sill to catch drips. It is also used as a lid to keep dust and pathogens as you transport the beverage from the tea room to the workspace.

Step 1: Step1. The Design.

A basic drawing was done of the project and measurements were taken from a variety of coffee mugs to confirm dimensions. The completed item would be cut from a piece of acrylic 9.5mm thick. Tea spoons were also compared to settle on an appropriate diameter for the spoon recess.

The measurements used for this item.

-D1 (circle for the main recess) = 84mm
-D2 (circle for the spoon recess) = 26mm

I draft of the 2D mechanical drawing was then done in a sketch book for reference.

Step 2: Step2. Design in 3dmax.

The easiest step. A 2D mechanical drawing was done in 3ds MAX by creating shapes based off of concept sketches combined with measurements.

All shapes in this drawing will serve as a boundary or a path for the machine to follow.

- Both inner circles will have material removed within to a specified depth using a slot drill.

- The Machine will follow the lines forming the text using a V-Bit.

- The Machine will then follow the circles and the outside shape using a V-Bit to slightly bevel the edges and remove the harsh 90 degree angle.

- The slot drill is used again to perform the final cut.

A simple 3d model is made and rendered to provide a preview of the finished item.

The final drawing is exported as a CAD .dwg format to be imported into Artcam where tool paths used to direct the machine are created.

This is a really cool idea, has it been mass produced before? Maybe you would be interested in doing a Kickstarter project for it?

Thank you!
I will consider doing a Kickstarter Project with my coaster-lid.
Thank you for introducing me with such a cool website! Haha

That's great! When you get the project up and everything, put the link here, I'll forward it to a bunch of people I know as well as some good spots on Reddit. Good luck!

Oh... Nice thinking there! I like the simplicity of the idea and the execution as well!
Nicely done!

And yeah... Why not try a kickstarter?

Haha, Thank you!
Kickstarter is pretty cool!
I will consider some more project to do with it. haha
