Do you have a photo of the assemble without the skirt in place?

I don't actually have any photos, but if you check out my YouTube channel there is a preview video of it running without the skirt on.

thanks, I think that answers what I was looking for, I had assumed the same.

will post photos of my build if it works out.

Awesome - good luck!

Great project!

What material do you recommend for printing out the parts?

I am leaning toward using a double-head vibrating motor for improved mass balance.
This double-head design is only available in 555 size (36 mm diameter, 50 mm length). Is a bigger 555 motor as opposed to a recommended 385 motor an overkill for this design?

Thanks for sharing this project!

Thanks!

I used ABS, but then again I use ABS for everything.... It has good springiness to it which is essential for the leaf springs, but otherwise I'm sure any material would be just fine.

Good idea with the double headed motor - I was planning to go down that route but never found a motor with the two weights timed the same on the shaft :-/
I think a bigger motor would probable be fine - I found that I was never running the motor anywhere near full speed, so as long as it is not super fast it should be OK.

Thanks for the additional info!

Yes, the heads on the motor need to be aligned in the same direction. There are quite some offerings on ebay and aliexpress, search for "vibration motor double head".

Regarding the springiness of the leaf springs - was it necessary to experiment with the infill / density of this part? The thickness and infill, together with the properties of the material must be important for this to work properly. What infill did you ultimately use for the leaf springs?

Best regards!

Awesome - I’ll check them out!

I used “dense” infill; the UP! Printers use proprietary descriptions, but at a guess I would say it’s about 85% infill, with 3 solid layers. All mechanical theory suggests that the spring is super critical, but I’ve found that you can’t really miss with the settings, so whatever you go for will likely work!

Wierd Fruitloops dispenser, still works. 10/10

Great job! Any instructions on which motors to use, what frequency, how to assemble, etc?

Thanks Anton! I had forgotten to put instructions up - whoops! Description edited now. The frequency will depend a bit on the parts you are feeding, but the lowest natural frequency motor you can use the better.

Awesome work! A project involving something like this is next on my list and heavily weighted so it should actually get done. Whenever I finish up a few other things I'm working on lol.

Thanks! Haha I know the feeling - the "to do" list never seems to get any shorter...
