Anycubic Mega Zero - Filament roller guide

Remix of https://www.thingiverse.com/thing:3052488 to fit the Anycubic Mega Zero 1.0.

REV04a: Increased bearing height with 3mm and made the bottom thinner so that filament is in line with the extruder.

In REV04b and 04c, the height is increased with 10 and 20mm and the bottom is not made thinner. Bearing is higher and the filament curves towards the extruder.

Depending on your setup and preference you can use any version.

If you need another height then please let me know and I'll adjust it for you.

Please enjoy.

**If you don't have a bearing, you can also print one : https://www.thingiverse.com/thing:2746804 You can see it in my setup
I am using REV04a myself in conjunction with my design of an upper filament guide https://www.thingiverse.com/thing:4628529.**

P.S. I know it's better to use a real bearing, but I just like the idea that you can print all the parts you need for this.

P.P.S. Added M4 n
