Last December I was approached by a friend to do a joint build on a better printer.
I took them up on the deal, because I had an IKEA drawer, where the plastic rail guide had broken, and I was unable to print a replacement part with either of my 3D printers.
I think it is fairly reasonable deciding to build a whole new 3D
printer to repair a piece of furniture which only cost 18EUR originally.
This model is an excellent stress test, because:
1. it is 200mm long, so with the pads it only fits diagonally on the heated print platform
2. has thin walls
3. well calibrated bridging is necessary
4. retraction is really critical (the small cylinders at the top)
5. relatively fast to print
6. it is big only in one direction, so wants to curl up enormously
7. perfectly levelled bed is necessary. PCB alone does not work.
8. we wanted to print it with ABS plastic (the more difficult one)
And it has not broken since then, so holding up fairly well
(5 months already!), and we use it daily.
I also published both models on thingiverse, as thing:31115.
Maybe others will find them equally useful.
1. The model was printed on March 5 using slic3r 0.7.0.
2. We used a 0.5mm arcol.hu v4.0.1 hotend at the time. (currently 4.1.1 is on the sale)
3. Red ABS from reprapsource.

I closed down the commenting on this webpage due to the enormous number of penis enlargement suggestions.
If you have any thoughts to share about this article, please discuss it on arcol.hu's mailing list, in this thread.
As almost all my previous buyer built a heated bed controller, and at least Bogdan have built one, nophead is using his brain controller to handle the heated bed temperature. So there left no choice, but build my own;-)
