Domino Creator! by Joerg Jun 26, 2011

Description

this is an OpenScad script that will create Domino tiles for you!

you only need to specify the size of each tile, the maximum 'eyes' you want (most common = 6; max. supported by now = 9) and the number of tiles to skip (for bigger sizes that cannot be created in a single run).

the main goal of this script is the placement of the domino tiles and calculation of the needed eyes-count on each single tile...
the outline of one tile isn't optimal yet - you are very welcome to create better ones (those are the modules one_brick to create the outline and eye to create one single eye at the top of the script).
[btw: the small pieces in the first picture are from an earlier/simpler design; I didn't tried the actual design with the small pieces yet]

because OpenScad does neither have working variables nor allows recursive module calls, the maximum amount of eyes is '9' (plus: the eye-placement for big counts like 12 or 18 could be messy).

Very cool! Wonder how it could be modified to generate two color prints for dualstruders.

Instructions

1. OpenScad: load domino.scad and call build_dominos(width,length,height,max_eyes,skip); with the arguments of your choice
2. OpenScad: render (F6)
3. OpenScad: export as .stl
4. import into ReplicatorG
5. print
6. repeat for bigger tiles...

note: if you create dominos which cannot be made in a single turn, the script will tell you, what value you'd need for the next turn:
"to generate next block, skip = nn", so you don't need to count the already printed pieces ;-)
- I marked that with a red rectangle in the 2nd and 3rd OpenScad screenshot, a bit small I must admire :-/ but at least you have an idea where to look for that hint...


I have included a single .stl for rather small pieces (10x20x4mm; 6-eyes)
plus all the needed .stl's to print more useable ones (20x30x6mm; 9-eyes)
beware those .stl's are for the HBP!, if you are running the ABP, you may want to adjust the max. print area, since the script is using the full area (see second picture)!
