Step 12: Command P

Although it shouldn’t be necessary at this point, you must ensure that all of the items that you want printed are combined into a single piece. This is accomplished as before with the Combine->Join function.

Export your file as a .stl
Currently, in 123D, you must first sign in with a username and password to enable all of the Save As options.

Now you are ready to print.  Several 3D printing services are available online, or if you are lucky to have access to your own printer, you could print out several versions of your own Super Personalized Candle Holder or make them for others.

Thanks for your comments on this Instructable’s clarity and room for improvement.
I will upload an image of the actual shadow as soon as one is available.  The speedy draft print didn’t include the internal cuts that require higher resolution. 
great work, but it would be more credible if you show the effect
Agreed hkhizer. I would if I could. That would require reprinting as the model never made it in one piece. I moved on...sadly. "Someday" I will have another one printed, but I'm too distracted
Wont the candle melt the 3D print?? <br>
nope. I had no problems with melting.
Of course you could have a design that is too close or too thick and the print will melt. Although I STILL haven&acirc;€™t see this up close, my print was made of plastic and thus could melt, but my design intent was to avoid that. <br> <br>I could explain away this issue with candle convection transport, effective surface area to volume ratios, or emissivity of the plastic, but thats just silly when I can say one way or the other when it gets here. -Jason <br> <br>
It seems like the width of your light source and its proximity to the light blocking elements would make for a very fuzzy edge on the projected shadow. Something closer to a point source seems like it would yield a crisper shadow. Maybe an led? <br>
A point source is ideal, but not necessary. IF the light blocking element was thin, then yes you are right, but they are multiple redundant elements. Its the same as using two almost closed irises for laser alignment or long shafts for picking out a single star only every thousand years or so. <br> <br>What was shipped to me was ineffective because of improper packaging (1/4 of the posts were broken), incomplete cleaning (support material was still surrounding many of the posts), and poor printing (in both resolution and the fact that the posts were curved!). <br> <br>My busy work life has hindered having alternative high-end printing services from attempting better.
Is it necessary to brace the posts if the posts are shaped differently? LIke in loops or something... <br> <br>And wouldn&acirc;€™t it be easier if the candle was taller shining down on the table?
So a solid chunk of material thats cut minimally will certainly provide the most support and create the sharpest possible shadow. Flickering or movement of the light source will not affect the silhouette, but its not as interesting. <br> <br>I actually attempted individually curved features at first, but wanted to explore arrays and didn&acirc;€™t consider patterns of hoops. I like that thought. <br> <br>For your second question: Sharper angles are better and a taller candle would provide that when projecting on the table. However, I was concerned about the candle shrinking so significantly that I would loose the light contrast completely. Votives were simpler for me, thats all...and cheap.
Why are there no pics of results? I would really like to see this thing in action!!!
I know I know! I still don&rsquo;t have it in my hands...<br>I hear you. I has been clearly printed, but I&rsquo;m awaiting delivery. They had to make several attempts because of technical problems on their end. They took a picture of it before placing it in the mail so that I would at least have SOMETHING to show. Thanks for your interest
Well 3d printers are a pain sometimes... Ill be keeping an eye out for the pics!!!<br>
Nice idea! :) <br>Is there an actual picture of the stand in use and throwing a shadow?
Not yet; the guys at the print shop had to take the photos in step 12. The final version is still being shipped to me.
