Filament Guide Slit for Lack Enclosure

This is my attempt to improve the filament guide on my Lack-enclosure. I used to have a straight guide through the top table as shown on the pictures. But that wasn't very ideal because the filament got bent way to much. So I just decided to make a slit in my table and print two inserts that fit together in the hole. Glue the top and bottom insert to the Lack-table.
