If you own a Makerbot Replicator, you might have seen some of the amazing colours they offer: http://store.makerbot.com/plastic/1-75mm-filament.html.

Unfortunately, trying to get a full colour palette (13 colours in stock) means having so much plastic you’ll never get through it all. Makerbot tried offering rainbow colour packs before, but they are now no longer for sale. I suggested it again via email, but it sounds like they’re pretty slammed with making Replicators :) 

Here’s the idea:

Standard Variety Pack – $100

Silver, Dark Brown, Yellow, Green, Red, Magenta, Orange, Blue

You get 1/8th of a spool (~ 150m) of each – for 1kg in total.

Electric Pack – $100

Light Brown, Fluorescent Yellow, Nuclear Green, Fluorescent Red

You get 1/4 of a spool (~ 300m) of each – for 1kg in total.

In searching elsewhere online, the only alternative I’ve found is Faberdashery – where the same deal would cost about $250 USD. I’ve done some back-of-the-envelope calculating, and I think a group buy would be an effective way to get a rainbow colour pack at cost-effective prices.
