The wife was having some issues opening the Purelife water bottles that we currently use so I designed up a Parametric bottle wrench that opens them quite easily. It is parametric because not all bottled water has the same size caps and Soda bottles are even a bit larger. So if you use Purelife Bottled water the cap is 27.4mm, which is model default. For a Pepsi bottle the size would need to be updated to 29.8mm. Just measure your cap input the one parameter and everything else auto updates

Having a detail keg that requires air pressure to operate I decided on the Xiaomi Mini compressor V2 So I drew up a quick mount bracket to attach it to the detail keg using a strap
