lol blowhole spirographs are a good idea! its like post modern art, except wierder and more pointless.
This has inspired me to do a case mod where i blow a nail bomb inside a case Then have lights shining out so at night it looks sweeeet, lol
Nice mod, I'm loving the "Oops I messed it up by letting a CnC loose on it" effect. Can't wait to see more
an 80mm cutter, call me a novice at milling, but that seems a bit excessive for a CNC machine? surely u could have got it to automaticly make a circle with a smaller cutter, say 10mm?, cutter would have broke only costing u about £5-£10
