I’m sure I’m not the only one who indulges and then gets… ideas. 
I mainly use the Tempest 2 in the garage in a dedicated area… but when I take it outside, it can be a balance with the YLL 3, the Reload 3 in its parts, and the T2 itself. I don’t really want a large tray that the pieces are loose on… I don’t want to have velcro pieces on the bottoms of these things or anything like that… so I’ve been playing with this idea.
Had a small board in the garage, 14" x 7". Figured if I cut it in half, one the one side I could shape 3 holes for the Reload pieces in use, and a slot for the YLL… slap that on top of the other half and I have a tray with a “cutout” for each piece. This way I can carry it all at once, and if I’m out back on the lounge chair it can balance in my lap.
*I don’t have carpentry skills or experience, and minimal tools… a hole saw bit, an old jigsaw, and a drill. Nothing else needed here (including skill 
, took me maybe 2 hours… with… breaks…)
Board:
Holes rough cut:
See where I’m going with this:
Attach it together: (also put rubber feet pads on, which aren’t shown. And the cheap board split, hence unevenly spaced screws)
“Finished” (for testing anyway):
Examples:
And finally, ensured there was room for the tube, just in case I need it with me:
I always use the Reload in its pieces as designed… so this should really work for my use case. Hopefully it gives someone else an idea… interested to see what anyone else has created!
