Customizable filament guide

Some time ago I installed for my Anycubic i3 Mega the spool holder from CuriousTech (https://www.thingiverse.com/thing:2555689) with return roller from enry68 (https://www.thingiverse.com/thing:2846692) because I have next to the printer little space. This system works really well. But now the filament sometimes hangs in front of the camera, which is attached to the heating carriage and has already got caught with it.
That's why I designed a filament guide with OpenSCAD. This part is attached to the extruder side mount of the spool holder. The guide is fixed with a M4 screw and nut and supported with a pin via the 2nd hole. The stability is completely sufficient.
(Sorry, the part looks a bit awkwardly, but it is completely sufficient for me.) On the upper side I attached a dust filter (https://www.thingiverse.com/thing:2349995). Perfect!
