When it comes to leasure time, there are not many activities, that are more exciting than 3D printing. After you printed diverse things from Thingiverse or any other 3D printing gallery, there is a great wish, deeply buried in your mind, to design stuff yourself to get the real excitement — and what is more obvious than upgrading your 3D printer with parts printed by itself/ yourself 😛
If this was the right appetizer, look how my Ender3 got upgraded with a full metal frontend or take a look at my Thingiverse profile with some other designs. If you have any questions, especially the decisions, e.g. why I designed the new hotend exactly as it is (a wide monster hotend) or suggestions, how to improve it, do not hesitate to comment!
