IMO, the splash guard isn't entirely necessary.
I assume it would be adding time & cost to the piece, and I find it's easy to avoid splash back by adjusting water levels/draw speed.
Unless it actually does splash up the neck regularly, maybe that could left out?
Also, maybe the ice pinches could be an optional extra?
Like, add $10 (or whatever you think is appropriate, Lev) if you want I've pinches.
I know EFS charges $25 extra to have ice pinches on a custom piece.
Ice pinches are a nice option, but I've only ever actually used ice a handful of times.
I find an 18mm joint to be a bit more convinient, as you can get a low profile 18->14mm reducer for like $10, and it looks a whole lot prettier than a 14->18mm enlarger.
