Bobblerz... just 'Bobble'. Very likeable little things (that are quick and easy to print) and bring a smile to your face every time you tap them down onto a sold surface (keep holding the body) and watch them... bobble.
They're a fun little head that bobbles up / down / sideways on an internally printed spring. Just give your Bobbler a shake and watch it 'bobble'...just like watching a fidget spinner spin!
Everyone that sees them likes them and most want one... so they make great little gifts... and as they require just 16 - 18gm filament at standard scale (....and yes they can be uniformly scaled up okay to a certain extent) they aren't expensive to print.
A range of Bobblerz .stl's is provided... choose your favourite (refer to images to see the selection) or print them all and create a family of 'Bobblerz'. You can even get creative with them by painting the eyes and mouth or pausing your machine mid-print and swapping the filament so you have your own unique Bobbler/z.
Bobblerz are easy to use / have fun with. Just hold the body part then tap them down onto a solid surface, hold them down and don't let go. This makes them 'bobble' best... if you let go much of the energy is lost into the body through vibration so they don't 'bobble as well or for as long. The body part is important as it provides a holding mechanism independent of the internal spring but also limits the sideways spring movement minimizing the chance of breaking them (...because PLA is very brittle).
Competed prints will have four fine bridges which have been designed in to stop the Bobblerz from bobbling during printing... as that would cause all sorts of print issues. These bridges run from the top of the body inwards to the neck section. They should be quick and easy to snap away to leave your 'Bobblerz' free to bobble... have fun with them!
You can also add colour the facial features to make them stand out more. If you decide to do this using an enamel paint and very fine brush is recommended. Felt tip pens and acrylic paints are more prone to running / smearing.
These are all easy prints on accurate / precise well set up machines. However, do not use any automated support or you are likely to end up with a spring that isn't springy so a Bobbler that doesn't bobble.
Please refer to the print settings and images for additional information... and post images of all your 'Bobblerz' for other members to see.
