Accessories for bottle dryer with fan

I've used the powered bottle dryer by cmh and wanted to improve the look and handling.

I've designed a “sleeve” or “shroud” for the original print. 
To fix it in place you will need two M3x30 and, if the fan is rattling too much, two M3 nuts. 

I added three versions of it: 
- plain: no holes for either a USB cord or a button (if you want to drill your own)
- cableguide: one small hole in the side to pass through your USB/fan cable
- button: includes an additional 7mm hole for a locking push button (I'm using these: https://amzn.to/3GgJQy8). They are press fit plus a dab of glue.

As I also have flexible/soft flasks that are a pain to dry, I've also created a super simple adapter to dry smaller ones (limited by the height of the printer). 

I'm using a 5v 5015 fan and connected it to an old USB cable. This can then be used with a 5v USB brick.
