'Willpower' is something people are often heard saying they need more of... like when they start a diet, want to get fit, aiming for a challenging goal. Making changes in what you do and/or how you do it usually takes a fair degree of... Willpower'.
Now you can get more... 3D print your own 'Willpower' battery pack. That's the fun/novel idea behind this simple print. However, done right it's another great example of what you can do with 3D printing because the 'Rotating' version has a sleeve that spins around the Centre part.
The process is very straight forward... print the Sleeve first (including colour changes if you want). You need to print this first so its ready for later in the process...
With your Sleeve completed print the Centre part but pause your machine almost at the end of the print, slide the Sleeve onto the uncapped Centre section, making sure it's fully seated at the base of the Centre part, then finish the print.
The change point is critical. You have to pause it at 47mm (with a 1mm Raft). Any sooner and the extruder/nozzle will hit the Sleeve.... any later and you won't get the Sleeve on because the cap will have started to be printed on. The cap part seals the Sleeve into the print. To make identifying the point easier for people without Z-pause on their machine the design includes a small notch. When this starts appearing pause your machine. (Refer to the images).
When printed with mid-print colour changes the result is impressive... give it a go!
There is also a Solid type for people wanting to print some 'Willpower' for themselves or as a novel gift to give to someone when they need it....
Recommended points are:
Sleeve Colour changes at 2mm / 44mm with a 1mm Raft.
Centre part Sleeve insertion point at 47mm (or as soon as you see the notch start appearing (Refer images).
Solid type can be changed at 1mm / 3mm / 45mm / 47mm if you're keen to make it look like a real AA battery (0 - 1mm and 47 - finish should be the same colour as they represent the contact points on a real battery).
People are sure to find this fun, so a great little gift, and the rotating version (combining 2 parts into a single moving thing) is another clever application for 3D printing that will amaze people.
