Weekend Contest: Give Marvin superpowers!

75
By on Contests

The BlenderNation weekend contest has been away during the vacations, but now it’s time to bring it back! I’ve teamed up with 3D Hubs, the local 3D printing network. Their mascot, Marvin, is in need of some adventure and could use some superpowers!

Marvin (who has his own Twitter account) says:

Hi Blender-folks! I'm Marvin. I'm not a human, but people love 3D printing me and showing me off.

Rules:

  • Download Marvin.blend to get started.
  • Add any kind of accessory or pose.
  • Keep the model 3D printable (mainly, make sure surfaces are closed and parts are not too thin). For more info, see the ‘Blender for 3D Printing’ course on the Blender Cloud.
  • Keep the result ‘family friendly’ ;-)

As with previous contests, post your submissions on the comments and vote up your favorite entry (in case of doubt, I'll ignore anonymous votes). The winners are picked on Tuesday, and the top-3 winners will receive $30, $20 and $10 in free 3D printing on 3DHubs.

Have fun!

        I was considering running Marvin through ZBrush Dynamesh but I wasn't sure if it was against the rules to use that kind of task outside of blender. I wasn't' really happy with the remesh modifier results but I guess it will have to do for now.

          Yeah, I tried to use zremesher to fix it but it wasn't much better. I even tried to re-topologize it manually, and it just wasn't worth it. I even considered just making it from scratch as someone did below. Once it sunk in that the 'contest' was essentially to make an accessory (or give him super powers, which I'm still not sure how you'd 3-D print most of the ideas that come to mind) I just forgot about the topology. Even though the edge split modifier 'breaks' Marvin, I didn't really care because that wasn't the contest.

          I was convinved that any idea I came up with, printed at the needed scale, would lose any details, but I was wrong. The one e5dy printed for someone else came out much better than I thought it would. Kinda makes me with I had stuck with some of my original ideas instead of going with a bad idea and not being happy with it. I doubt I'll even post mine.

    I'm no expert by any means, so some of these 'tips' may be completely wrong, but might save some people a couple of minutes.

    Fix the origin. It's nowhere near the geometry.
    If you're going to use smooth shading and/or a subdivision surface modifier, use an edge split modifier first. (I don't think there'd be much need to use a sub-surf modifier, but I did test it just for kicks and noticed the result is awful without the edge split modifier)
    The scene is set to blender render, which isn't a big deal, but might cause a tiny bit of confusion if you're used to opening blender with cycles as the default renderer.

    Thought there was something else but it's eluding me at the moment.

      Edge split will separate all of the edges, which is the one thing you absolutely CANNOT do when 3d printing.

      Subserf just doesn't work well with this mode

      actually this modele is very small and you don't have to subdivide it more

      as you can see on the printings pictures on thingivers, the faces are totally smoothed by the printing resolution

      • Roger H. on

        The blue one looks exactly like it does in blender with flat shading, but yeah, I said using the subsurf was probably pointless. It's usually something I do with models to see if there are any vertices not connected or if something went wonky.

        And yeah, as I said about the edge split modifier...I kinda forgot the requirement that it be 3-D printable. I was still caught up on topology/rendering issues, sorry. When I saw what smooth shading did to a simple render, I got caught up on it instead of accepting it. I suppose if it's tiny, it really doesn't matter.

          the most important to stay in mind is the thickness, walls under 0.4mm (0.4 blender unit, 3D print takes the millimeter as base unit) are not printable and under 1mm very weak

      Companion cube! I missed you so much! Sorry I've thrown you into that oven back there in chamber 17. Can you forgive me? TT_TT

    YAY! The weekend contests!

    Super power: Water Power

    Accessory: Trident and Water

    First version is color second is no color

    (For 3D printing the water will be removed)

    Enjoy!

      It is probably a million miles away from being 3D printable, but I thought I'd throw it out there.

      Also I remodelled the base model to get better topology. So if anybody wants the remodelled one with unapplied boolean modifiers and quads everywhere, just let me know. Although it's not complete and not an exact copy.

      I like concept, and printed effect... even it is simple suit...
      Thanks for my next inspiration... The Marwin War Mech Suit.. :D of course out of the competition ;) just for exercise
      And please do some suit mod for "Andre" model it deserve :)

    This is my modelling exercise... At least...

    Marvin have some magic power in him self, that blow my imagination out..., i always want to make some printable stuff. Even if i'm not 100% sure that is printable...
    But concept is that, that orange parts should be printed separately. And one figure concept / one solid mesh... "Because i'm Marwin!!" ;)

    e5dy Thanks for Marvin.blend file, that save me some headache

    Happy Blendeing to All

    Here is mine. I was actually going to give him laser-vision but I eventually decided to go with freeze ray eyes because it seemed a lot cooler (no pun intended) with a modified frost shader I had leftover from another project. I originally had a gradient background with a lot of lights before deciding on relying heavily image lighting because I am terrible at lighting things manually. my animation wasn't the cleanest but because the GIF framerate I let a lot of mistakes slide. The first version looked so bad that I was about to quit before I gave it another try.

      I forgot to show an Image of the mesh for 3D printing. (I don't own a 3D printer so I guess I will just show the OpenGL Render.)

    Wasn't gonna post this, but thought someone might at least get a giggle out of it. It's not a super power, and even farther from being a 'proper' accessory, but....

    It's Carvin!
    Pretty sure it would be 3-D printable, but it's solid, so certainly not 'proper'. The tires started out as a spaceship, until I realized my idea for a 'bubble dome' wouldn't 3-D print, or at least not transparent like glass, so it turned into a tire. Not sure why an alien would have a car (with no steering wheel of course) but since he doesn't have arms, his 'super-power' is driving a car with no arms/steering wheel. Kinda hard to print 'telekenisis'.

      Not sure why your image doesn't show, but I kinda like your 'Iron Marvin'. It does look like your image is hosted on discus, so not sure what went wrong. Thought maybe you posted it somewhere else and linked to it, but even then it usually shows the linked image in the post.

          I have the same problem all the time, you just need to give it a few minutes and refresh the browser. I'm not sure what it is with blendernation but I don't have that kind of problem on other disqus forums.

      Think Bart will tell you he can't delete any posts unless something has changed. It's probably not a big deal since they were all posted so close together. It's worse when someone posts something, and thinks it didn't post, and people vote for it, then they post another, and people vote for that one.....

      If you do get votes on different 'posts', Bart will just add them together, but again, doubt anyone voted for any in the last few minutes.

    Hey everyone, due to marvin's lack of hands the best i could come up with was giving him a rocket shoe to kick evil's butt!

    I think it could be printed with some adjustments and probably using a printer that allows supporting material (i'm not an expert , but my printer should arrive in a month yay)
