Introduction: Mason Jar Astronaut Sensor Light

The Astronaut Mason Jar light is a quick and simple weekend project. the idea is to use the Mason jar's classic form to make a figurine head that can be illuminated with LED inside. an astronaut figurine is what I had in mind first. the Head is enlarged to emphasize the mason jar element and makes the overall proportion cute. the concept is quite simple, design a body and 3d printed it. attach the mason jar, wire the lighting component then attach the helmet. the result is quite amazing, the Lighting component has a music sensor so LED will flash with the music, which makes the figurine quite attractive as a desktop mood light. Lets begin with the design process.

Supplies

Mason Jar

70mm diameter, preserving Mason Jar by Bormioli Rocco, 250ml. this mason jar is the right size for a figurehead. a 120ml smaller size is okay as well.

Lighting Component
Music Sensor String light/ Copper Wire Fair Light. I picked a 3meter long string light for its compact size and brightness

The Rest

2 x 3mm wood screws

grey spray primer

acetone for gluing ABS 3D printed parts

File and Sandpaper for the post-printing finish

acrylic paint (optional), marker,

Step 1: Design Process

I designed the astronaut figurine in 3ds max. First I found some astronaut image reference, then worked out the scale of the whole figure. the yellow part is a rough estimate of the Mason jar. The one I used is roughly 70mm diameter at the lid, 88mm at the widest part in the middle, and 90 mm in total height. I made the helmet to encapsulate the whole jar so the overall shape of the head is somewhat a rough barrel form. I made the legs bending slightly to bear the load of the glass jar and enlarged the feet so the figure is stable. the body part has a hollow core to direct LED into the head cavity internally.

the backpack is kept minimum with a flat surface. I could then attach an alternative solar panel in the future.

the whole figure is then sliced into different parts for optimistic 3d printing orientation.

Step 2: Set Up Parts for 3d Printing

Updated: all the STL had a scale issue previously, now they should be the right scale. I have also fixed the mesh in the legs file. everything should be fine now

For the best result, I can think of. I divided the body parts into the following pieces

Left Arm, Right Arm, Left Body, Right Body, legs.

smaller parts eliminate a lot of support materials needed. I own a fairly old printer, so failed prints are quite common recently. this way can easily manage the result and time.

the helmet in two parts separate at the widest part. the helmet is meant for joining at the end of the assembly. so don't glue them together first, otherwise, the jar won't fit into the helmet.

now just be patient and let the printer do its work.

Step 3: Inspect 3d Printing Parts

I printed all the parts in white ABS. I use ABS filament because I can glue it with acetone for the post finish process.

break all the support and cut any obvious seams.

while I am waiting for the helmet to finish. I started on the post-finish process.

Step 4: Glue and Post Finish All the 3d Printing Parts

I first sand all the joining seam smooth. Then I used acetone to brush on both sides of the joining surface. glue and press them together. the gaps are filled with 2-parts epoxy clay and sand it smooth again. have some patience. once the legs and arms are all glued to the body we can move on to the painting process.

Step 5: Painting Astronaut Figurine

I applied spray paint it with 2 layers of gray primer. After the primer is evenly applied, any seams and gaps that are previously hard to see are shown now. I used a fine metal file to remove any imperfection. Finally, I applied the 3rd layer of primer. and wait until it is dry.

to add more definition to the spacesuit I applied white acrylic paint on top of the gray primer. I used the dry brush technique, so the white paint only covers the raised surface and left the crease and concave surface gray. the helmet is done the same process.

2 layer primer -> sand ->one more layer of primer -> fully dry -> white paint cover.

once all the pieces are done we can move on to assembly.

Step 6: Assembly

1. Guide the copper wire LED through the body core.

2. Screw on the Mason Jar lid. drill a larger hole in the middle.

3. Before attach the glass jar. place the lower helmet in place first. shove all the tiny LED inside the jar. then attach the glass jar tightly.

4. glue on the upper helmet with super glue.

Step 7: Complete!

Switch on the light backpack! and enjoy the light show.

the music sensor really makes the figurine interactive. it is perfect for desktop display.

Please give it a try and Enjoy!

Hi - this is great!!! Can you tell me which Music sensor strip light you have used? I'm finding LED-strips, but they are too big for the mason jar. Thank you, all the best from Vienna - Stefan

How did they work out? I am considering using the same lights.

I bought the mason jar from Amazon but it's too small inside the helmet.
I downloaded the stl and loaded them in Slic3r with no modifications, and printed with Pronterface.
What is the correct diameter of the neck hole?

Question 9 months ago on Step 1

Is there any way to get the full 3d model that isnt separated so it can be printed as one solid piece?

Question 9 months ago on Step 2

Again a question: When opening your 3D-parts in my slicer (PrusaSlicer), they are very tiny. For which final size should I go - to make the mason jar fit afterwards?
Back again: The legs will not work out for me. The walls are to thin, so in the slicer there are "empty layers" errors. Do you have other files available?

I have updated all the files now. they are to the right scale, give it a try again;)

Thank you - everythings fine now - I already printed all the stuff and the body is glued together. Will post pictures, when finished.
But there is always a last question :-) : Do you have the complete body also as STL? I was just thinking to give it a try and print it all in place. I think with some supports my Prusa can handle it - what do you think?

I try to increase the size to 1000%. it will work. i also uploaded the legs file again.
let me know if there is any other problems

Hi, me again :-) - now I used the new uploaded legs - but it seems, they do not fit to the body. I printed both with 1000% scale, but the size/angle of the feets seems to be wrong. Pls see picture attached: blue: old legs 1000% scale, orange: old legs 1000% scale. And which scale do we have to use for the other parts (helmet, body, ...) - maybe you can upload also that one in the final size? - Thank you anyways for your great work!

Hi, I double-checked the files should be okay. download the legs V2. they are the right size. the measurement of the legs in my printer is x:102.20mm y:68.40mm z65.06mm. I think the orange one in your printer is the right file. hope this helps
