Description
The Latching Button Fidget Toy has a piston that can be pressed in. It remains hidden until the button is pressed. The button releases the piston and it snaps forward with a satisfyingly loud "click!"
Simply, press the piston until it clicks. Then, press the side button and enjoy that snap!
This quick print consists of three pieces: a piston, a latch with a button, and a case to hold it all together. All three pieces print in about 1:45. The entire assembly is powered by two pen springs.
You'll need to provide two pen springs to power this print. The springs need the following dimensions:
If your spring is particularly stiff, you can use one spring. I used two springs because I like the strong tactile feedback.
The print has a 0.3mm tolerance between moving pieces and a 0.2mm tolerance between non-moving parts. This means it's a pretty forgiving print, but you should still take some precautions when printing.
Avoid elephant's foot and brims, and remove all strings. Any remaining or excess plastic will interfere with the action of the mechanism.
Check the piston's fit in the case. If there is any resistance, the piston will get stuck. I needed to clean up the inside pocket of the case on two prints. A quick scrape with an X-Acto blade worked perfectly.
The video above includes assembly instructions. I suggest watching that before attempting to assemble your print.
