Long live Mongo (our 100watt laser cutter)!
To ensure the ongoing health and happiness of Mongo, we'll take him offline for maintenance for a couple of hours. Some lucky person may be picked to test the filter-changing documentation. Not to worry, it's really easy. Some ability to lift 15-20 pounds is required in the disassembly and reassembly of the filtering stack. Afterwards, you will have bragging rights and the undying love and respect from the Nova Labs community.
Note: Although it sounds involved, it isn't, and does not require the prerequisite Laser safety/usage class. This would, in fact, be a good introduction to how some of the innards work.
