The original Designers model is a great design. The only change made was I reduced the height of the channels. This reduces the amount of filament used by 100 grams and reduces print time by over 1 hour.

Additionally, the holes were enlarged to accept a threaded heat insert:

If the designer makes this change, I will remove my design.

You will need the front and rear ends available from the designer:
