Filament Guide for 40 x 40 or 40 x 80 ALU Profiles

This is a snap fit filament guide for my Felix TEC4 3D-printer but should also fit to other printers using the typical profiles 40x40 or 40x80 as in my case. The oval version ist the one I'm using actually.
I included my older round version (with slot) if one prefers the smaller one. The one without slot in the photo isn't available anymore and I deleted the files.

Use 50 % infill or more to make it strong enough. I tried it also with less, but in this case the snapping part broke.
