Going back in time and looking at the oldest active thing on Thingiverse. Phooky's 1st stellation of a dodecahedron was a laser-cut design demonstrated on 1.8mm acrylic (with the protective stickers still on).
This version is an extrusion of those 2D designs, with some parameterizations and modifications to make the edges touch up to each other.
Printing
No supports are needed. Models are already oriented in the correct direction so the proper side is lying on the bed.
There are 3 different versions:
- Original
- Mimics what the output of the original thing would be like.
- Flush (Recommended)
- A version of the geometry where the slots have been modified so the edges touch.
- Flush (Loose)
- A version of the geometry where the slots have been modified so the edges touch. This one has looser slot geometry, which was needed for parts from my PrusaMini+ to interlock correctly (where the PrusaXL needed the Recommended, or else it was too loose).
Pick one of the versions, print a Connector and a Triangle model, and test if the fit when connecting them feels like it slides in well but has a good amount of friction-holding force. If so, print more copies to the correct quantity:
- Triangle
- x60
- Connector
- x90
Assembly
Assembly is straightforward, but refer to the video if needed.
- Assemble the 5-sided cones.
- Connect the cones together.
When assembling, keep in mind the face lying on the bed usually has the better finish - so that surface should face the outside. This probably makes this thing a good candidate for textured or holographic transfer bedsheets.
Source
The Blender source file is also included. It is parameterized to vary the sheet thickness and tolerances.
The parameters can be located as custom properties of the PARAMS object. See their descriptions (can be accessed as hover-over tooltips) for more details.
See the embedded notes file for more information and params used for exporting.
