    @czahl said in Blog: czahl's build:

    the new update from @kirk where the inner diameter is increased from 2 to 3mm.

    Also good catch, @danielfp248 has tested this already and it results in smoother flow/less pressure drop in the system without introducing new leakage it appears.

    @kirk hah, nice to hear. I was already thinking that this was unnecessarily tight.

      @sepi It was necessary when I had a much worse printer, lol. But I think any decent printer should be able to handle the wall thickness when the holes are 3mm on both the reservoirs and the flow frames.

        Printing the larger parts gives the impression that I'm almost done, but there is still a lot work to do...

        I'm still waiting for the silicone foil, should arrive next week. BTW, has anyone tried to "mill" the silicone foil and graphite foil? I'm thinking to put it below a 2-3mm wood plate and use my OpenBuilds CNC router for it, wither with an engraving tool or a 4mm endmill...

          @czahl Thanks for sharing! Looking great so far! We usually cut the silicone gaskets either by hand or with a vinyl cutter (I used cricut for it),we've never tried something like what you're suggesting. Let us know how your approach goes!

            BTW I love seeing everyone's different PP and PLA colors building very differently looking kits!

              @czahl I haven't tried milling those materials but was considering similar options to what you have in mind. I'd give it a try at least, the more optoons we have, the better. And cutting gaskets will always be a thing in RFB production I'm afraid.

              The alternative would be to simply get a drag knife like this: https://fr.aliexpress.com/item/1005006131524919.html

              Also, congrats on printing the rest of you parts! They look very nice!
