Ultimaker 2 Filament Guide
youmagine
I designed a custom filament guide for my UM2 since the stock guide kept letting the filament jump out. It needed to be captive, holding the filament securely in place. That's when I stumbled upon NeonGreen's design (https://www.youmagine.com/designs/improved-filament-guide-for-ultimaker-2), which was a great starting point but still didn't meet my needs. The filament wasn't being held captive in the correct orientation, so I used that as inspiration to create a new design that would securely hold the filament on both sides.
