Introduction: Hammer of Probability
First Instructables project by Neil Ricamata, Vandan Patel, and Sean Martinez for the STEM Practicum senior class at the Keller Center for Advanced Learning (KCAL).
- 2'x4' 1/4" sheet of wood
- 3D filament
- Vex Screws
- 2' long 1.125" Diameter Dowel Rod
- Laser Cutter
- 3D Printer
- 3D modeling software
- Drill and Drill Bits
- Allen Wrench
- Sand Paper
- Adobe Illustrator (for the laser cutter)
- Miter Saw
Step 1: 3-D Models
We created the joints to connect all the triangles in Inventor.
- The first joint was for the top piece of the Probability Hammer.
- After that was done we cut the initial joint for the rest of the joints to save filament.
- Thereafter, we created the joint that would go around the 1 1/8 inch dowel.
- The diameter for the holes were 0.160 inches and extruded all the way through.
- Then, we started to 3-D print these joints. We printed 1 Top joint, 1 Dowel joint and 10 of the “B” joints.
Step 2: Probability Triangles
After those designs, we created 5-inch equilateral triangles in Adobe Illustrator. So, then we can easily transfer them to the Laser Printer Program.
- We started to Laser Print the triangles.
- We printed triangles like this leading up to the #20.
Step 3: Putting It Together
Once the pieces are done we started to assemble the Dice.
- If you want you can make it exactly the way of a 20 sided dice, use the template located on top to number your dice.
- Make sure to drill holes in the triangles to match up the 3D models
- Make sure to put the joints in order (Biggest joint goes at the top of the dice & the one with the hole goes at the bottom)
- For the dowel joint make sure cut the triangles and sand it down to smoothly place onto the dowel.
Step 4: Finishing Touches
- We used the lathe to sand and create a small pommel
- If you want, you may add a wrap to the handle to make it look more EXQUISITE!!!
