I saw a few paper towel dispenser for Weber Q's but the Baby Q is considerably smaller, and the existing dispensers wouldn't fit the paper towel.
It will fit the standard 9" / 220mm paper towel width (Up to around 260mm max). I haven't tried a extra large/supersize/double length roll of paper yet.
I placed a slightly smaller cardboard tube between the LH rollers and RH rollers to make it easier to mount. If you want a thicker roller i have included the roller from SeveQ's design.
I used 4x 6G *18mm Sheet metal screws to secure the holder to the side table.
I used Luumi's holder for the accurate and snug mounting holes, and i used SteveQ paper towel holder with a mod to allow you to fold the tables up without the paper towel falling out.
I plan to revisit this design at some point in the future as this current one does not allow me to fold the side tables inside the weber for transport, I may produce a modular/removable mount for one side.
You will need to print 2 of the holders and 2 of the rollers (unless you want to just use a different tube to hold the towel in).
