Print in place Ratchet Noise Maker, Rattle Clacker

Celebrate your sporting team and add even more fun to the proceedings. It's also just a great fidget!

This prints in place (PLA) and manages 92dB at the size in the profile with just 30g of filament. It would also make great party favours.

Printing

The printer does not remember flow calibrations between prints, so to reduce the chances of stuck print in place models such as this I recommend ensuring you tick that option. There is a 0.4mm tolerance though which should be enough, I've printed with 0.3mm and less without issue.

Strength

In testing I had some handles snap and thought I would need to adjust the design so it was wider at the pinch point, I tested more walls and infill but it kept snapping. In the end I discovered I had a couple of filaments (Admittedly a year or more old) that snapped easily at any point along the handle. I tested other prints and found the same issue, brittle along the layer lines, so I concluded that the filament just had poor layer adhesion.

I then went to a fresh roll of Bambu Basic PLA and the print settings in the profile and found that the handle was strong enough, I could bend it without it snapping so published with the current settings.

You may wish to increase the walls and infill depending on your filament, but it should not be necessary. I've read that walls add more strength than infill.

Customisation

The main profile is just one colour the other are examples of colour changes. To edit or create your own slice the model and then drag the vertical slider on the right to where you want the colour to change and right click. This brings a menu where you can add a colour change if you are using the AMS or add a pause if you want to do a manual colour change. To do so when the print pauses go through the menus and just unload and then load a new filament.

Disclamer

Use sensibly and at your own risk. I'm not responsible if you whack someone while enthusiastically celebrating! Or if it goes flying off and hits someone / thing.
