Summary

A hand operated animated heart Valentine.

Video of prototype is here: https://www.youtube.com/watch?v=F6l6FjOTfgU.

Designed using Sketchup Make 2015, and printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" Settings (.2mm layer height, 2 shells, 10% infill).

Happy Valentines Day (also my birthday)!

Instructions

Study "Assembly.skp".

Print and assemble all pieces as shown in "Assembly.skp". I found "Heart.stl" prints best when the build plate is a little further from the print head than I normally set it. After printing, carefully remove the hold down pads on "Base.stl" and "Frame.stl".

Test fit and trim, file, sand, etc. all parts as necessary for smooth movement of moving surfaces, and tight fit for non moving surfaces. Depending on the colors you chose and your printer settings, more or less trimming, filing and/or sanding will be required. Pay close and careful attention to the small gaps between the pieces of "Heart.stl", making sure to remove any flashing and/or debris with a hobby knife or equivalent as "Heart.stl" must move smoothly without binding.

Assemble as shown in "Assembly.skp".

Lubricate all contacting moving surfaces with light machine oil.

After final assembly and test, I apply a small dot of thick cyanoacrylate glue to heart lobes and point to hold "Heart.stl" securely if "Frame.stl".

Comment if you have questions.

Happy Valentines Day (also my birthday)!

Anyone try printing this at a reduced size? Say 75% or 50%

I will be printing this cool design for my girlfriend for Valentine's Day (Which happens to be my birthday too!)

Thank you, I hope it works well!

Happy Birthday to you from a fellow Valentiner!

Silly question, whats the point of the extra circle part on the point of the hearts and the top cover. will that just snap off?

Not silly at all!

If there’re what I think you are referring to, I used them to increase the surface area at corners and/or sharp points to minimize warping on the build plate. And yes, they simply snap off.

Greg

Thanks for that. I thought thst would be the answer.

Comments deleted.

Have you thought of putting a little LED light in there? It looks like a 3V coin cell battery and a single LED could be fit in there. I was thinking that instead of having an external power switch, you could fit a small microswitch, similar to the ones used in 3D printer endstops. A cam somewhere on the crank arm could light up the heart only when it's fully extended.

the heart piece works really well if you print it at .5

Thanks for the input, hopefully others will benefit from it.

Many thanks again.

Also I had to glue in the crank arm attached to the crank because pulling the Handle of would make that arm come out

trop mignon, je prend pour ma femme :)

Really cool design!

Thank you very much, I'm glad you like it!

Thank you so much for posting so many great things! What do you do to finish your prints? After you take them off of the build plate, do you sand them, or...?

Thanks!

Thank you for your very kind words!

I do very little to finish them. Once in awhile, if the build plate gets too close to the print head, residue from the painters tape will stick to the piece and I'll take the time to sand and clean that off, but other than that, nothing at all.

Thank you again and I'm glad to hear you like my things!

That is a great movement. Reminds of the Tom and Jerry cartoons where Tom would see that pretty white cat for the first time:-)

Thanks!

I should have included that in the "what inspired you" section...

;)
