actually this is a better representation I can go 17 degrees still not enough though 
If you want to think outside the box (pun intended) How about an accordion slider? Cut all your acrylic into 3" strips and then join them with clear vinyl. Cut tracks for the side.
hmm good I idea but I think that would be rather complicated and hard to keep air tight
Doesnât have to be air tight, you just have to have more negative pressure on the inside. On my giant laser cutter itâs open bottom but my exhaust fan pulls so much air that itâs not a problem.
The one Iâm using on the giant cutter was a pain to get and uses 900w of power alone but there is a similar one with the same specs and uses less power. https://www.amazon.com/iPower-GLFANXINLINE8-Hydroponic-Conditioning-Pre-wired/dp/B00CAHM75W however considering how small an x-carve is. (My laser is 4ft c 3ft cutting area and the build chamber is 6ft x 5ft) I bet you could get away with a 6" model.
hmm interesting I wonder if I could get a 3d model of that unit or some extremely accurate measurements so I can model put it into my model
I would doubt it. These darn things change every other week. Iâve used a bunch of them. However there are several of them on Amazon Prime so you could order/measure/return them. 
Also on my cutter I just mount a flange on the case and then put the blower under it. https://www.amazon.com/Ideal-Air-736359-Flange-Kit-8/dp/B00W1RDII6
and what do you do about a charcoal filter is there one built into that blower or is that something separate
They are completely separate but I exhaust outside and if youâre cutting acrylic donât use just a charcoal filter. It wonât get all the toxics out and youâll be dead. You need serious filters for that. http://www.instructables.com/id/Build-a-laser-cutter-fume-extractor/ or if you want to go pro and have lots of money⌠http://fslaser.com/Product/MediumPurifier might be more your style.
