    ABS is the only choice available in a local library. I will still try out 0.10 mm setting, though it's double the duration. But looks are not so critical, will be an honest indicator that some illegal parts have been used in my builds :)

    Finally got to print the tester with Prusa i3, 0.15mm and ABS. Best fit seems to be 0.9 / 5.0 which seems to be as good as original Lego. Not the prettiest print though.

    Very nice esthetics.

    Thanks (for amorti too)! I have built that without the tank, just didn't connect the dots.

    Is the compressor some Lego part or something that you build?
  6. pekka111
    Sorry what is a compressor? This is an interestic topic. I'm wondering in what kind of cases you have to use pneumatics instead of gears, axels and actuators.

    Got any video?

    I'm not getting notifications from this thread... Worm gear is good idea, that is probably best way to produce the required force for the switch. I have the ones with two holes. e: This could also work: https://brickset.com/parts/4528037/linear-actuator-10-15-m

    Thanks! We have cheap printing here in public libraries so maybe I'll do a test.
  11. pekka111
    Thanks :) I guess 3D printing is difficult, since you would like the tolerances to be quite small. Is there a reliable (Chinese) brand that makes original looking and durable parts in those missing sizes?

    Beginner question: all the beams have odd number of holes? Half beams have 6 hole version but not one with 4 round holes? So do you cut custom lengths if something else is needed?
  13. pekka111
    I agree 100%. And since you won't (usually) make parts, you have to use a bit of imagination when making things work.

    Good to know that genuine switches might get looser over time.
  15. pekka111
    This in nice invention. I meant that because the switch is so tight, you have to have a long lever for it. Btw I just got some new used switches and they are easy to work with and would work like in your video. The ones i got earlier are so tight that legos would break first. They are hard to move even by hand. Maybe they are faulty. e: just noticed new/used switches have label "mould king" on the side :(
  16. pekka111
    Thanks for the answers! So with longer lever and gears you could move the switch. But now that I think of it, if you have the second motor for moving the switch, you can also use it for a second pump and have two separate lines? Inspired from msk6003's video, I tested connecting cylinders directly to each other. They work utilizing over- and underpressure, but that action seems quite stringy. But you could transfer movement in both directions with one motor that way. And by using springs. Do you know if that switch requires as much force?
  17. pekka111
    Is there a motorized switch for pneumatics? Manual switches (47223) require so much force that doubt they can be automated. Do pneumatics wotk always with overpressure? So there is no reverse function with suck / underpressure?
  18. pekka111
    Thanks! Looks like quite nice selection even in my country.

    Any tips for getting sensors? I got some 88007 distance/color sensors but missing all the rest. Do you know if there are any sets that have sensors, other than Education sets? There are some cheap second hand sets with power functions, but there might be some latency if you use them through infrared connection (https://docs.pybricks.com/en/stable/pupdevices/pfmotor.html).
  20. pekka111
    I wouldn't mind the short distance of infrared but if no support in pybricks... Bt remote 88010 mentioned here seems to work so that it is. Thanks for the help! <rant> And looks like my 88012 hub would be useless without pybricks. Just tested with powered up app. I wonder why lego makes this stuff so unnecessary difficult. </rant>
  21. pekka111
    Okay so next question :). What is wrong with infrared? I don't have the parts yet but got a cheap offer for Lego 42030 set with two remotes and sensors.
  22. pekka111
    Hi, is it possible to have physical remotes (not phone app) with a pybricks system? Especially i'm interested in infrared. So I would like to program some automation with pybricks and add some manual controls too.
  23. pekka111
    Awesome examples here what can be done. And I don't know any system that can do so much with ready made parts.
  24. pekka111
    With Lego it's easy to get started. Then after some experience, maybe I'll find that they aren't enough but nothing lost in that situation, just move on to other systems.
  25. pekka111
    Yes, and some pneumatics too :)
