This is a 3D printed LED lamp project that looks like a giant knob. Turn it, and watch it glow from the inside.

    This instructable is meant to be a companion to the webinar series I'll be hosting starting March 15. Design Now: Hour of Making in Motion will focus on mechanical assemblies and integrating electronic parts in Fusion 360. Follow this link to register for free.

    Step 1: Tools and Materials

    All the parts can be purchased on Amazon. You can also buy the hardware on McMaster-Carr, which may be more convenient because you can make an order through Fusion.




    Any filament will do, but I like the results I get with Alchement Wood Fiber PLA. It's out of stock on Amazon, but I think this one will have pretty much the same look:


    <p>JON-A-TRON, i'm a new member just joining the building instructables team could you possibly give me helpful advice on a project im working on ? if not that's ok i'll still make it i would just care for some help write back to me if you are interested sir.</p>
    <p>Sure, what's the idea?</p>
    <p>Nice job and certainly gives me some ideas - since I am a woodworker (and a 3D printer is not in my immediate future), I immediately though of a turned wood knob version. And further I thought this would make a very nice night light for a children's room. All kinds of potential. I did sign up for your 3D printing class and already have Fusion 360 downloaded. Now to reconcile more stuff to do on an already overloaded 'to do' list.</p>
    Thanks for joining us! I hope you're able to expand your skill set. Woodworking + 3D printing is a powerful combination. A turned wood version of this would be gorgeous. You could even do it with a super thin wall and make it glow from within.
    Trying to make a wood turning thin enough for light to pass through - probably (in a practical sense keeping in mind physical strength limitations and skill level of wood turner) not practical. But combining a layer approach with wood and plexiglass or another plastic - that might work!
    <p>Maybe something with wood and epoxy/resin. Tint the resin.</p>
    <p>I was just thinking the same thing when I first saw this except mixing epoxy and phosphorous zinc and embedding it with wood seep through the cracks for light to shine through as a unique design or electrocute the wood to even exotic look. So many ideas flowing through my head of endless possibilities. Nice work John-A-Tron. Dee18 like minds think alike. ;-)</p>
    <p>Turning one was the first idea that came to my mind seeing this, before reading the title even. That would be beautiful, share it if you make one!</p>
    <p>Hello! It looks awesome and I want to make it. Can you upload the base.stl file?</p>
    <p>Oops! Just added it.</p>
    <p>Thank you!</p>
    Great job and great idea! Just one thought before everyone goes to copy it. To keep consistancy remember &quot;righty tighty, lefty loosy'. What do the rest of you think?
    <p>Yeah, it's kind of weird. Turning it to the right seems natural because that's how all knobs work (volume knobs, etc.), but this somehow feels like it might be turning the wrong way just because it's so big I guess.</p>
    <p>Looks good. If you could hide the supply it's just a big knob on the wall!</p>
    Should be easy enough with a junction box. It's low voltage, so there's no need to worry about fire.
    <p>Looks good but I suggest you kmprove your understanding of British slang.</p>
    Walked right into that one, didn't I?
    <p>I was slightly disappointed when I clicked that link, but it's still a pretty sweet lamp.</p>
    Sorry to get your hopes up.
    <p>*teehee*</p><p>Ace lamp though!</p>
    <p>cool design - lighting really makes it stand out. </p><p>PS: nice comment policy prevents me making a lewd remark at the title, so I won't. </p>
    It's not that kind of lamp!
    <p>Jon, to get more light, you may consider making the lap &quot;taller&quot; so that there is more space between the wall and the base of the knob. I think that this would give more light without taking away from the theme. Make sense?</p>
    Yeah, that would probably help. The main thing I think would be make the rim shallower so that the LED strip is expose more, that would give it a much wider throw.
    I really like it. How hot does the material get from the LEDs? Concerned about longer term lighting with the design. Have you done any testing? Thanks
    The literature from the company has thermal information. This setup gets barely warm to the touch.
    <p>Really nice looking and great way to turn it on! love it!</p>
    <p>Thanks man!</p>
    <p>Amazing! Thanks for your share</p>
    <p>Thanks for saying so!</p>
