3D Printed Parts
There's a total of 28 parts the need to be printed. They're listed below in a table. The d2m-spike-face.stl part will need to be printed 18 times. The d2m-frame-a.stl and d2m-frame-b.stl parts are not the same / duplicate of each other. d2m-frame-a.stl features an opening for the d2m-led.stl part.
d2m-pomel.stl |
The "butt" of the handle. The pushbutton goes here. |
Print in any material. |
d2m-handle.stl |
The battery, Adafruit Trinket and JST Switch breakout goes in here. |
Printed in Wooden PLA Filament. |
d2m-rod.stl |
The rod connects to the handle and the cap. |
Print in any color filament using a large brim for better bed adhesion. |
d2m-cap.stl |
The cap is glued to the LED holder and connects to the rod. |
Any color filament. |
d2m-led.stl |
Holds NeoPixel Jewel and is glued to the cap. |
Translucent PLA |
d2m-shell.stl |
This is the icosahedron shell. It should be printed in white or transcluent PLA to diffuse the NeoPixel LEDs. |
Translucent PLA |
d2m-frame-a.stl |
Half of the frame that is glued to the outside of the icosahedron. |
Printed in Steel PLA filament. |
d2m-frame-b.stl |
Second half of the frame that is glued to the outside of the icosahedron. |
Printed in Steel PLA filament. |
d2m-spike-face.stl |
Print 18x of these. Glue onto each side of the icosahedron - exept for the top face. |
Printed in Steel PLA filament. |
d2m-spike-top.stl |
Bigger than the spike-face part, ment to go on the top face of the icosahedron. |
Printed in Steel PLA filament. |
Reorient Parts Flat on Bed
Do not print the parts "as-is". You'll need to reorient the parts so they're flat on the bed. Use your best judgement so they do not require any support material. Most slicing programs will allow you to select a face and place flat on the bed of the 3D printer.
Large Parts
Some of the parts, such as the rod and handle are fairely large and may not fit on the bed of every 3D printer. these could optionally be printed in halves and glued together.
Support Material & Rafts
Although there are no support material or rafts required, I do recommened adding some brims to the parts for best bed adhesion. The d2m-rod.stl file is a rather tall part (180mm) and could easily topple over while printing, so a large brim can help keep it on the bed of the 3D printer.
Post-Processing & Finishing Techniques
I printed the spikes and the d20 frame halves in Proto Pasta's steel composite PLA. This material can be sanded down and polished using a rock tumbler or polishing compound. The only other parts the were sanded down was the rod. This was sanded and spray painted with a nickel / silver color, which gave it a smooth finish.
Download & Remix
If you're interested in making changes to the design, the source is public so you can download it the original in many different formats such as IGS, STEP, SAT, Google SketchUp, etc.
