it's more than an ad and the levels of HCN produced while even printing nylon at "Safe" temperatures is way below any problems period, with nylon printing you'll die of CO poisioning first and that is if the right temperature are exceeded!

A CO alarm is warranted this box is so over kill it's not even funny, however on an other note a box like this if your motors are under run current wise may come in handy to prevent warping.

however if your running your motors at spec the motors might just over heat because with a heated bed that chamber will definitly reach 60 to 70C during a decently sized print optimum temp to avoid warping however not a good temp for the motors

Printing with ABS can produce low-levels of HCN, but during normal printing the levels are well below safe limits. If you have a well-ventilated room, it should not be a problem. If you have an enclosed space or no circulation it is a good idea to get some ventilation, you may want to do this anyway because the fumes can be unpleasant even if not toxic.

There are background levels of HCN in the environment anyway, and these are not dangerous. HCN is toxic because it prevents transport of oxygen. In general the effects of HCN go away when exposure to the gas is removed, there are no significant cumulative effects at the trace levels emitted by printers.

ABS plastics do emit significant levels of HCN if they are burnt, so this should definitely be avoided. If you have some ABS catch fire, ventilate the area and leave it for a while.

PLA does not emit any HCN. Other plastics like Nylon may emit more HCN, and I would advise caution if using those polymers.
