USB charger mount for 22mm handlebars

This is a case and mounting for those cheap 12V USB chargers. You can find them on eBay or aliexpress or else. The case offers enough space for the charger and cable slugs.

You will need also:

3x M3x 30mm cylinder head screws
3x M3 nuts
1x some anti-slip covering between mounting and handlebar

Print without supports. The threads need to be clean.
