Three weeks ago we started adding a free Olsson Block set with every sold Ultimaker 2 and Ultimaker 2 Extended. We'll continue doing this for a few weeks because we believe it is a great example of what the community contributes to Ultimaker. And the Olsson Block can definitely be a valuable addition to your Ultimaker.

You guys carry a lot of knowledge, helped countless of users and continue to contribute to the Ultimaker ‘Universe’. Obviously, you deserve something for this too!

So for the next few weeks we will host a 3D printing contest.

This week, we'll focus again on the more refined expertise in 3D printing. Lets see who got it dialed down best!

We would like to see the smallest working 5 or 6 geared bearing.

You can change it in Cura all you want, but no modifying of the tolerances!

A tip; experience with the first layer. When it is squeezed as usual the first layer will probably solidify and you'll have a hard time getting it to work.

Every week we’ll have a new winner who wins a special edition Olsson Block set.

It contains the same set of nozzles we share with our new users, but especially for you we have added the 1.0mm nozzle too, for the super fast prints!

To draw you the full picture, it contains the:

 

  • Olsson Block itself
  • 0.25mm nozzle
  • 0.4mm nozzle
  • 0.6mm nozzle
  • 0.8mm nozzle
  • 1.0mm nozzle
  • a screwdriver and socket to swap nozzles

 

The other rules of the contest are pretty simple.

 

RULES

 

  1. We know how you all love hacking and modifying, so we have only one guideline: it must be printed on an Ultimaker with a 0.4mm nozzle. Besides that.. everything goes!
  2. Print as small as possible, but it has to work!
  3. Entries must be uploaded in the Print section. (Fill out your settings if you want. The winner agrees to share his settings at the end of the week)
  4. Share the link and a picture of your upload in this thread.
  5. Add at least one picture in your upload which illustrates its size, like by adding a ruler, digital calliper or something like that.
  6. Everyone can participate in every contest, but you can only win once.
  7. There will be only 1 prize per contest

 

 

EXTRA INFORMATION

 

  • *We will choose a winner based on size, but aesthetics as well. Small is great, but it also has to look like a good print!
  • We will announce each weeks winner on Monday in the corresponding thread on our forum, on our Twitter feed and Instagram!
  • You can participate until Sunday midnight CEST.

 

 

WHAT DO I NEED TO PRINT?

This model is something most of us are probably familiar with. Hopefully that experience reflects in the entries!

We would like to see the smallest working 5 geared bearing.

Courtesy of Emmet Lalish for letting us use his model, thank you :)

Alrighty then..

Ready? Set? Print awaaaaaay!

    haha I knew someone would notice :p

    Hopefully, it's on my Ultimaker in the office waiting for me.

    And hopefully, the bottom layer did not turn into 1 solid layer this time ;)

    It should be uploaded in a few hours :)

    We ran an unofficial contest a few months back, but that never lead to a winner or anything.

    A lot of people seemed to have enjoyed it, and since we have a lot of new participants I figured it was a good idea to do a re-run :)

    Thanks @Labern

    As the scale decreases on this bearing, it seems like the ability to tolerate axial forces decreases. At a certain level the bearing loses the ability to act as a thrust bearing with even slight axial pressure causing the bearings to start to buckle. At even smaller levels the rotational forces causes individuals bearing to spiral out and the whole thing self destructs. Moving from 5 to 6 bearings helps some.

    Even gripping the outer sleeve at these scales can cause it to deform which also causes issues. Definitely challenging.

    I have only added a "shaft" to make it easier to move, while I was going down and down fingers started to be too big :D

    Ultibot's Travels: Going Home

    The season of storms was fast approaching and Ultibot realized he had been far from friends and family for far too long.  It was time to say goodbye to the Lilliputian bots. It was time to go home. Before Ultibot left, the Lilliputians bots threw him a grand party and the greatest dancer in the land performed The Dance of the Gear Bearing in Ultibot's honor. At the end of the dance, the only thing left to say was goodbye.

     

    Print here. Gear Bearing scaled to 0.249 with a diameter of 12.873mm and a height of 3.73mm. For small scale prints it becomes as much a photography challenge as a small print challenge. Video above shows a mark on the outer rim and a small dancing bot to show that each gear is turning individually and is not stuck in place.

    Congratulations

    ...

    @GrPiotr91!

    You won the special edition Olsson Block set with your 7.99mm print bearing! Awesome, great job! Could you explain what you did that allowed you to print this small?

    Keep it up for our next contests guys!

    For the contest we are going Dutch! :)

    We'll start within a few hours, stay tuned..
