Printrbot simple metal 1403 Bowden Conversion

thingiverse

So I need to make my Printrbot Simple Metal to have a Bowden extruder because the piece of junk is to heavy and makes the surface finish very ugly. I plan to make it double bowden, but I go one step at the time. Stay posted for new part for an outdated machine that I refuse to let die. And none of the setups I found are good enough. Not to mention the crazy and useless extruders that are most of the times, overkill. I used the Old ceramic Ubis for the photos, because I have not installed it yet, I have an UBIS 13s. I will update the parts and photos when complete. Also, there is no objects like these anywhere on any STL repository, even on yeggi. This thing was made with Tinkercad.
