### Step 5 - Keycaps
* There're many choices.
* Homemade bottle cover keycaps

* XDA 1.5U color keycaps

* About the homemade process.
* I bought these inexpensive 3gram/5gram distribution bottles just to get the covers (28-30mm diameter).
<img src="doc/homemade_bottles.jpg" width="50%">
* Cut the shaft/socket out of regular transparent keycaps.
<img src="doc/homemade_get_shaft.jpg" width="50%">
* Drill some holes on them so later we can apply UV resin better.
<img src="doc/homemade_drill_holes.jpg" width="50%">
* Apply UV resin, glue the socket and the cover together.

* Don't forget alignment.

* After cured by UV light, they look like this:
<img src="doc/homemade_cured.jpg" width="50%">
* If you have resin printer, you can make them by yourself.
* Make half-transparent resin by mixing translucent and white resin (5:1) as the base resin.
* Mix some drops of UV resin pigment, you can make all Pop'n Music button colors.
<img src="doc/color_pigment.jpg" width="50%">
* 3D file is **/PRODUCTION/popn_keycap.stl** or if you're using Chitubox - **/PRODUCTION/popn_6keys.chitubox**. Orientation and support should be like this to get perfect button surface.
