stingray

gudo and neotko congratulations on an ingenious and apparently very successful design! I've been a long term 'lurker' on the forums here, and have been using an Ultimaker 2 Extended since soon after they were released to make architectural models. I was a long time user of Makerbots before the Ultimaker and see the Bowden tube system as the only downside of what is otherwise a much better machine than any of the Makerbots. We often print extrusions that vary only small amounts in the x and y over the duration of a print, such as walls, boxes, towers etc. As such the inherent inaccuracy of the elastic Bowden tube is very noticeable, particularly with layer heights of say .3. We need to print relatively large things quickly and neatly and don't care too much about strength. I think generally the 3D printer market doesn't cater very well to us architects. I would be extremely interested to see a bill of materials and print geometries for this 'add-on' and would be equally excited if you were to offer it as a commercial product. I've come out to join the forum to ask this; I hope you'll welcome me aboard the Ultimaker forum train! Thanks for your hard work.
