Alfawise U30 Support fan 40x40 with support for comparator

thingiverse

I've tried many fan supports but think that the one designed and built by Freedzy is absolutely the best, it's adapted for the original fans of the Alfawise U30 and creates a perfect air flow when printing. However, in my opinion, there's a flaw: it wasn't designed with adding a support for a comparator in mind. I believe that to get excellent prints, the planarity of the print bed is essential. So I bought a comparator: https://amzn.to/34Le6Lm Unfortunately, all the comparator supports I found couldn't be assembled on my Alfawise U30 with the fan support from Freedzy; in fact, they're all designed to work with the original fan support of the U30. Therefore, I decided to design my own comparator support and then integrated it with the excellent fan support existing. The result is a complete support for both fans and comparators. How do you use the comparator? 1. First, level the print bed **without** the comparator but always with paper. 2. Next, insert the comparator and level it again, take one of the angles as reference and press the "Zero" button on the comparator. That level will be what to obtain on the other 4 points on the plate using the knob. 3. Level the bed making that all the other 4 points are at zero. 4. Finally, before launching the print, it's very important to **REMOVE THE COMPARATOR** Update 08.17.19 - I made version 2 because in version 1 the software didn't export everything; now it should be fine.
