Negative Clicker Parts for Any 3D Model
A pair of negative modifier STLs designed so you can add a cheap tactile keyboard clicker to any 3D model — the same way I use negative cylinders for embedding magnets.
I’m really pumped about a new design tool I’ve been developing in my workflow: a set of negative parts that let me (or anyone) drop a satisfying keyboard clicker into just about any 3D printed model.
These little clickers are the cheap tactile switches you see in standalone clicky toys. You can grab them online for about 30 or 40 cents apiece. They’re small, reliable, and that crisp “click” is incredibly satisfying.
The problem I wanted to solve
I already use cylinders as negative modifiers in the slicer all the time to create perfect pockets for embedding magnets mid-print. I wanted the exact same reliable, repeatable process for clickers.
How I built the negatives
I started in FreeCAD, carefully modeling the actual hole/cavity geometry that the clicker needs to fit into. I printed a few test versions, tweaked the measurements through a couple of iterations, and landed on dimensions that grip the clicker securely without being overly tight.
Once I had solid positive “hole” STLs, I took them into Tinkercad. For each piece (the clicker uses two parts — one for the top and one for the bottom), I subtracted the cavity shape from a same-size cube. What came out the other side are clean negative volumes that work perfectly as slicer modifiers.
Now, in the slicer, I just drop these negative parts exactly where I want the clicker to live — top and bottom halves aligned properly. It cuts the precise pockets into the model the same way a negative cylinder punches a magnet hole. Super clean.
First models
I’m starting with a cute dumpling sitting in its little steam basket. I think the click is going to be a really fun interactive detail on that one. After that, I’m planning to work these into several other designs I’ve got kicking around.
Sharing the files
The negative clicker parts (and several of my other original models) are now available via my Thangs subscription. Makers can download the STLs for personal use ($5) or subscribe for commercial print rights ($3/mo, 15% off annual).

If you’ve ever wanted to add that perfect tactile click to your own models, this should make it dead simple.
