Step 8Now the fun part
At first I started with an X-Acto blade (standard type) to cut the oval shape out.
That didn't work well though, granted it got a lot of pieces out, but it was choppy and difficult (cutting through rubber).
So using my Dremel with sanding bit I went in and sanded out the whole.
Keep in mind here you are NOT cutting out the entire square drawn, but just an oval shape that fits within it. Do NOT cut a square. Seriously, you'll ruin your shoes (more so)
As far as the curves of the sensor went, it was more a matter of estimating. Someone with extra time could probably go and measure the radius's, but for me it was more a matter of starting smaller, and testing by trying to put the sensor in.
The cut marks made earlier (optional step) are nice because they'll give a rough estimation how far you should sand down. Also they help to ensure that the hole is flat at the bottom. If you didn't do that step, you could probably just do it carefully by checking the depth very often.
