Introduction: M.A.P.S. Keychain

About: Just an ordinary person who loves #thinking and #tinkering

After a long break, finally I decide to post once a while. And yes I am confuse how to write something about simple 3D printed object because we simply download the file and print right away, so no making-story to tell.

M.A.P.S. Keychain is not something related location, map, geography, or something like that. M.A.P.S. stands for Multi-Angle Phone Stand. Since my latest hobby is watching Netflix Serials, I love making phone stand that I can carry with me all the time. Some of initial fresh idea is specifically designed for my Sony Xperia XZ1. I made it thin and lightweight (20 mm x 50 mm x 4 mm) based on my previous work Magnum IDs And Stand. Since it is not universal then I do not post it even on any 3D community site. This M.A.P.S. Keychain (I will later called it Maps Keychain -- tired of retyping the dots) is universal and you get several angles to enjoy your favorite movies.

As a bonus, it also served as fidget because there is a center part you can spin. When you are in a hospital waiting room, you forget to bring your earbuds and you may not play movie because the sound may bother the other patients or visitors, you can sit down quietly and spin.. spin... spin...

Not fun, but a little better than playing a-stone-role.


A 3D printer.

Step 1: Files

Made of three parts and easy to assemble without manuals when you see the cover photo. Align the holes on both the body and spinner then plug the pin inside. Those three parts can be printed at once with orientation like this :

I use Cura slicer and some important settings to check are :

  • Layer height : 0.16 mm (this affected the pin and hole to be plug-n-play).
  • Infill : 20% (doesn't really matter anyway, but more infill = more rigid = more steady).
  • Support : Yes. Touching buildplate only.

The rest of settings depend on your material and preferences.

Step 2: Just in Case ...

In case you printed it with "fine resolution" (smaller than 0.16 mm layer height or smaller print nozzle size) and you find that the pin is too large to fit in the spinner's hole, you can use a small file to fit it in.

What if you print on "draft resolution" (more than 0.16 mm layer height) and the pin is too loose to bite the hole? This was what I encountered because I wanted to reduce the printing time. You can deform plastic with heat. Heat the tip of the pin with a lighter. Two or three seconds, close but not touching (I am working with PLA material). Press the tip gently on your table or any flat surface, to get desired radius on the tip of your pin to bite the hole.

Tip : Remember to wait for few seconds to let it hardens before trying to fit in the hole. You can repeat the heating process until the pin bites firmly in the hole.

Step 3: Angles

Angles you get will be different according to the shape and size of your phone or if you are using a soft-case or not. Only a few cents of material or maybe a dollar on some print services. Go ahead, try it and maybe this will inspire you to remix my build ;)
