TPU Foot for Steamdeck Controller Dock by JagerBombastic

Hello! Here's a way to add a TPU foot to this controller dock. While it is slightly more grippy than the hard plastic of the dock by itself, a dedicated silicone anti-slip pad will work A LOT better. This is just an option for people who don't feel like buying one, or can't order stuff like that where they are.
There are 2 files. "TPU Cutout" and "TPU Foot"

Import the version of the dock you want to use, into your slicer. Then right click on the model, and select "Add negative volume", then click on "Load...", select "TPU Cutout".
The cutout should load in the correct spot, and it should cut out ~.6mm worth of material from the model once sliced.
It probably won't be super pretty, but your printer should be able to handle filling in the gap. Of course, you can use supports if you really want to. They came out just fine on my C1 when printing with PLA and no supports.

Print "TPU Foot" in TPU, and use some kind of glue to secure it to the model. This sticks out aprox 1mm from the bottom of the print, depending on how much droopage/glue you have), and has .2mm clearance on the edges from the cutout. 

I printed the foot on a textured sheet. I found that the top layer had slightly more grip than the layer that had the texture from the sheet. A satin sheet may give similar or better grip. A smooth sheet should give the best grip. BUT, remember to use a release agent such as glue stick, as TPU can stick VERY strongly to a smooth sheet. You can add some water to the glue to make it thinner, to prevent streaks and bubbles. This should get you a smooth surface in the end, which may provide better grip. Ironing the top surface may work as well, but I've never tried ironing with TPU, so IDK if it tends to cause heat creep or any other problems.

I completely missed the STEP files in the original model. So if someone wants to make their own version using them, please go ahead! I still very much consider myself a beginner, starting to become intermediate in 3D modeling.
