Description

TMR posited it might take half an hour to make a d20 in Sketchup... it took 35-40 minutes, including figuring out a good process.

For the record, I used TopMod to generate the original twenty-face regular solid (it's an icosahedron, I believe, but my memory may be faulty), and I also cleaned up in Meshlab (couple clicks just to make sure the mesh was ok).

It Skeined great, at least for the jumbo size dice.

Place the dice in your 3D view with the 20-side facing down. Set the infill very high, slice it and save the resulting gcode. Then change your infill settings to be much lower and slice it once more, again saving the generated gcode.

Now, pick a height at which you want the weight to transition from low to heavy - I don't know anything about weighting dice but perhaps something like 40-50% of the overall height will work. Search for that height value in each gcode document and splice them together at that point so that the first half of the document is your high infill and the second half is your low infill.
If I wanted to rig this die so it rolled a 20 more often, how would I do that? Would I just mess with the infill?
What is the size of the die, and when it prints, would it be hollow inside or solid? (very very new to 3-d printing so I'm kind of clueless when it comes to this stuff)

Print, roll one hundred times, taking note of the results, and report back here so we can tweak the randomness ;-)

I'm a little confused how to print this; my MakerBot leaves a loopy mess on the lower faces.
May I request one with 20's on all sides?
Have you seen the joke spherical die with a single '1' printed on one 'side'?

:-)
*slackjaw* Yep, that's the Sketchup advantage alright. Check my dicepack for the other dice if you get ambitious :3
