The AprintaPro PrintaKit has the right idea, but if you’re reading this, you’re probably already way too invested in 3D printing to need one.

This would be perfect when bundled with entry level printers.
It’s kind of encouraging to know that 3d printing is simple enough now to be accessible to people who can’t be bothered to do enough research to see that $90 for that kit is hilariously overpriced.
@Thomas_Herrmann Good idea - only, for the absolute cheap end (think “Anet A8” level), this kit goes for roundabout half the price of the printer kit - quite an investment, if you’re on a tight budget (albeit a very useful one, especially if you’re just at the beginning 
…)
@Ingo_Ulrich The Printafix 500ml alone costs 50 EUR and that will last for ever. So essentially you pay 30 EUR for all the other tools and the bag. The Anet A8 Level is quite a bit too low. Don´t know why everybody is hyped except the price. Would´nt buy it.
I just recognised that the smaller bottle is included in the kit so it really is a bit overpriced.
