Cool thread

My 3D printing story goes like this. *deep inhale*
Let's go in the way-back machine about 4-5 years ago. At the time, Lego just stopped selling the original UCS Millennium Falcon and the price tag for ONE 47996 was $200 easy. I had trouble sleeping one night and had the thought to 3D print this highly sought after and super rare lego piece and make some moolah.
So that night I got up and found a cad file for the lego piece and found out the actual Length to Height ratio was incorrect and needed to be modified, so I then installed a trial version of AutoCAD and found some YT tutorials on how to tweak the file so it'd be identical to the original piece. Luckily for me at the time I owned a Lego MF to verify the incorrect size.
I got the changes made and now the question was how to color match it to the Light Bluish Gray color lego uses. Trust me, after researching, no one wants a black one or a black one painted (chips off easily even with primer paint). So I scoured google and found a company in Wisconsin that makes colored filament (I don't recall the name, sorry). I shipped them a few big LBG colored lego pieces and got 5 spools in the mail. It wasn't 100% accurate, but 99% accurate, definitely close enough and better than I expected.
Question two, how should I make it? At the time I knew 3D printing was difficult, so I found a shop 1/2 mile from my work and had them make me a pair for $10. The mods I made to the cad file were correct, yay!
I quickly posted my product on ebay with comparisons to the original regarding size, color, shape, flexibility and with it installed in my lego MF. I sold them for $99/pair plus shipping. It was a booming success, I made just over $4,000 profit in about a year and some change. During that time I did get a Creative something or other model of 3D printer, but returned it soon thereafter because of numerous headaches and it's just easier to have someone else do it.
The money I made spawned another spin-off company to Lego (after I showed them the market opportunity) where they specialized in replicating Lego Star Wars UCS sets, on the cheap. Those were more legit knock offs where they actually used molds, etc, but the quality was sub-par I read online.
The wife and I went to the Bahamas and stayed at an all inclusive resort for a week when my son was about 1 (stayed with the grandparents). Not a bad way to spend a sleepless night
