If you look at my other published models, you will see that I love fidget toys. I've been eyeing some of the high end fidget sliders that are available for sale online and are machined from exotic metals. Given the high cost, I decided to try printing a slider myself to see what these sliders were all about.
For this particular model, I decided to remix someone else's design because they had come up with a really cool way of sealing the magnets into the slider so that each half of the slider is a single, solid part. This makes for a very clean design and the only extra step required is to add a pause within Prusa Slicer to allow you to insert the magnets into the partially printed model before resuming and completing the print (see photo).
My change to the original model was to replace the top of the slider parts with something that was a bit chunkier and includes a knurled top to allow you to move the slider parts around in your hand.
You will need to order 6x3 Neodymium magnets off of Amazon (you will need 8 magnets per side) and you must make sure that you insert all of the magnets into the partially printed model in the same direction. You also have to make sure that when you insert the magnets into the second print, they have to be in the direction that attracts them to the the first print. This is easy to do if you leave all the magnets stuck together in a row and then use the stack to insert the magnets one at a time. Hope this makes sense.
A few more things: I printed with the infill at 90% to give the parts a bit more heft and I printed at 0.10mm FAST DETAIL to make sure the sides were nice and smooth. I also had really good squish on my first layer and this results in a very smooth and slippery surface for the sides that are touching/sliding together.
I printed using Prusament Opal Green PLA and it looks very cool.
Enjoy!
The author remixed this model.
Remixed the top of the slider to make is a bit chunkier and easier to play with.
