-## Code Example
+But I did not like this design and wanted to add more depth so I started over
-Use the three backticks to separate code.
+
-```
-// the setup function runs once when you press reset or power the board
-void setup() {
- // initialize digital pin LED_BUILTIN as an output.
- pinMode(LED_BUILTIN, OUTPUT);
-}
+Add more height and smoothed edges and
-// the loop function runs over and over again forever
-void loop() {
- digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
- delay(1000); // wait for a second
- digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
- delay(1000); // wait for a second

+and 2 tools path one roughing and one for finishing. I left 0.5mm of material in the roughing for the
+finishing pass
+
+
+
+Unfortunaly I measured the piece of wax I had and found out I can only fit 2 of these. So I had
+to go back and change the set up for 2 legs
+
+
+
+
+And rerun the tool paths
+
+
+
+And I started to mill

+## Rubber mold casting
+
+Now we are ready to move to the next stage
+
+I decided to use [OOMOO 30 Silicone Mold Making Rubber](https://www.smooth-on.com/products/oomoo-30/) for the rubber mold
+
+
+
+
+I set up 2 cup with equal amounts of each as per the instructions
+
+
+
+Both go into mixing cup
+
+
+
+A full 3 minutes of shearing
+
+
+
+And it is fully mixed
+
+
+
+Next I pour it in form the corner and let it flow over the mold
+
+<iframe width="560" height="315" src=../../images/imagW13/M85.mp4 frameborder="0" allowfullscreen></iframe>
+
+I left it for 6 hours to cure
+
+
+
+It easly came out
+
+
+
+And ready to cast the feet
+
+
+
+
+## Plastic casting
+
+I used [Smooth-Cast 300 Liquid Plastic](https://www.smooth-on.com/products/smooth-cast-300/)
+
+
+
+
+
+I has a 3 min put life and 10 min cure - so I have to move quick after it is combined
+
+
+
+Equal parts and 1 min of shearing
+
+
+
+Poured into the rubber mold
+
+<iframe width="560" height="315" src=../../images/imagW13/M97.mp4 frameborder="0" allowfullscreen></iframe>
+
+All set to cure
+
+
+
+
+It turned white as it hardened
+
+
+
+And we have feet ready to go
+
+
