Regarding the acrylic bending: get plenty of extra tubes

make a few test bends where you look for the sweet spot (not too stiff not too.. Flat?..) the acrylic can burn easily if you're not paying attention for a sec. Never stop rotating the tube so the heat can spread evenly.
Might help too if you look for some youtube videos where they give you a clear how to.
Heating the tube very well to make it wobbly af isn't the best approach either, as it will expand the diameter of the tube slightly. Imo it's good to try and bend it a bit while heating. That way you'll notice if the tube needs some more heat or if it's good to go. Keep some pressure applied too for a few minutes otherwise a 90° bend might flex back a bit, giving you a 95°ish bend. The hardest part is getting the measurements right for a second bend
