Don't tell your apartment complex you HAVE a 3D printer or laser cutter.
Threaten to SUE their bank accounts DRY over it if they find out and raise a stink. None of their stinkin' Bizznuss.
My first apartment out of college tried to ban all "semi automatic" firearms from their complex and gave me a rash of nonsense over my AR15 when they found out about it. They got referred to both the family attorney and the NRA. Backed them down really fast.

If a rule is ABSURD, I HAVE NO PROBLEM VIOLATING/IGNORING IT. FREQUENTLY AND REPEATEDLY...while telling the rule "author" to KISS MY BUTT. Yeah, I'm that guy.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
