CNC-milled 90s Style Retro Keychains

About: We make innovative digital fabrication machines. Our ZMorph 2.0 SX Multitool 3D Printer is one of the most advanced desktop rapid prototyping devices on the market with interchangeable toolheads enabling one...

90’s are becoming the new 80’s - an ultimate source of retro tech and vintage gadgets to make you stand out in the crowd. With the four retro designs available in this Instructable you can easily create your own unique keychains.

To complete this project we used CNC PRO toolhead for ZMorph 2.0 SX multitool 3D printer, but these free STL files can be used with any type of CNC machine too.

Step 1: Original Designs Included in the Pack

The package includes four original STL files created by one of our designers. There is a boombox, cassette tape, gamepad, and classic Game Boy replica.

You can import these files into printing software (we recommend Voxelizer) in order to prepare them for CNC milling. Depending from the worktable of your machine, you can place several copies or various designs next to each other and customize them with names, numbers, etc.

Step 2: Tips on How to Make the Keychains

We originally used 6 mm thick plywood and 1.2 mm milling bit but thinner ones would also work (thicker bits will lose details!). Only minor cleaning is required after milling.

The only other thing you’ll need for this project is a metal keyring to attach to the wooden keychain.
