This page will go over the steps to create Design 1 of the PDS.

#### Step 1:

Begin by printing the .STLs for three-part mold that are found on the [Downloads page](/pds/downloads). Print 1x design1\_core.STL and 2x design1\_outer.STL. Supports are not necessary for printing.

#### Step 2:

Assemble the mold with the two outer pieces surrounding the inner core. Put the two clamps around the mold.

#### Step 3:

Measure out 25ml of Part A and Part B of the Ecoflex 00-30. Put both parts in a cup and mix together thoroughly with a spoon.

#### Step 4:

Pour the mixed Ecoflex into the mold slowly and steadily and stop occasionally to let bubbles escape. Fill the mold to the brim. Let the silicone cure for 4 hours.

#### Step 5:

Once the Ecoflex has cured, take the clamps off of the mold and use a screwdriver to pry apart the mold. Pull the cast off of the core.

#### Step 6:

Attach the lengths of 1/4" and 1/8" tubing with the luer fitting.

#### Step 7:

Insert the 1/4" end of the tube into the open end of the silicone cast. Secure a zip-around around it and tighten it into place, securing the tubing.

#### Step 8:

Connect the 1/8" end of the tube to the pressure sensor on the electronics.
