Anet A8 Filament Guide with opening

I printed Puddlefist's https://www.thingiverse.com/thing:2357589, but I realised I needed to un-thread and re-thread the filament to get it working. The less threading I can do the happier I am. I took it into Tinkercad and changed the guide, but kept the mounting plate and arm. Then I sliced a 1.8mm opening to allow filament to slide in. It works for me, but your milage may vary.
