Only real difference is that the chute hugs the printer more and the magnetic holes are a bit more aesthetically pleasing. No need to have to seal the top. These holes are for 12x2mm magnets but the holes are 13mm wide and 2.3mm deep to add some tolerance. Theres also a model without holes that you can download so you can add your own magnet holes in tinkercad.
The author remixed this model.
