Creality 3D Ender 3 - Spool Holder - Better unroll your filament
Description
Introducing the new Creality 3D Ender 3 I decided as a Mechanical Engineering Student to finally buy myself a 3D printer. While printing for quite a while now, I've noticed, that my filament spools unroll really unevenly, because the spool holder of the Ender 3 has a much smaller diameter than the filament spools. In the long term, this causes an unnecessary high lever arm for the extruder and damages the spool holder itself, because of punctual attacking surfaces and scratches. Here, I designed a very simple, cheap and fast solution for this problem. This spool pipe goes between the filament spool and the spool holder of the Ender 3 and fits perfectly. It causes a very calm and steady unrolling and leaves the spool holder undamaged. I have tried a lot of filament brands, which fortunatly have the same inner diameter to fit my spool holder. If it's not fitting especially in your case, just have it as an inspiration for the problem. I have included the .step data, so you can just change the parameters to your filament spool. I cut out unnecessary material accumulations, to save time and filament. If you have any further questions, just contact me. I will give my best to communicate about your ideas and questions. If you want to spend me a coffee, feel free. But only, if it's bearable for you :) Best greetings to this awesome community.
