Raspberry ice cake
A 3D printer or 3D Printing service
sketchup make. http://www.sketchup.com/download
Autodesk meshmixer. http://www.meshmixer.com/download.html
download "3d animation -blackberry, raspberry, rubus" from User "Rubus" on googles 3d warehouse by searching "raspberry"
open in sketchup, &
download stl plugin from googles extention warehouse via "window" in the menu in your sketchup program.
then export as stl
repair this stl @ https://netfabb.azurewebsites.net/
download vine leaf right by miodragd (but my repaired edition) @thingiverse http://www.thingiverse.com/thing:714034
open the repaired "raspberry" model in meshmixer
then click "import"
it will ask wether to "append" , "replace" or "cancel".
go to your repaired "vine leaf" stl, and click "open".
Meshmixer will ask wether or not to repair the new models larger faces. choose yes.
Now the models are in meshmixer, you need to know how to navigate. use youtube tutorials for better explanation then mine;
click and hold right mouse bttn = look around(move the camera)
pressing "c" centers the screen to the point of your cursor at that moment.
zoom with your mouse wheel scroller.
more knowledge is for later. lets go with this first.
if you don't see a small window called "object browser", go to menu "Vieuw" and click "show object browser".
you can see in that object browser your two imported models.
ignore the magnet symbol behind your model name, click the eye on and off, just too see what it does. its handy for later.
Now resize your Vine Leaf until propper size by
selecting it in your object browser
clicking on "edit" (left) wich makes a new menu appear.
in that new menu, choose "transform".
Now, for each axes, you get a straight arrow, wich moves the model along that axes.
and a bend colored piece, wich makes you tilt your model on that axes. just click, hold, and drag.
@the end of the axes indicator there is a square appendix, wich is used too stretch the model on that specific axle.
@the center of the arrows, there is a small white box. click, hold and drag up or down to scale your model.
test some, and ctrl-z ;)
These are the basic navigation you need to complete this instructable, for further tutorials, please refer too a search engine :D
So scale your leaf, drag it into position, rotate it till its cosy, and click accept.
Now select that leaf in object browser, and Mirror it by clicking "edit" and "mirror"
meshmixer will give you a plane to pull in order to define the mirroring point in relation to the original object.
if u pull it far enough, a new , mirrored object will appear next to it.
also edit transform and drag this mirrored leaf in place.
now select all objects in your objects browser, and click "combine" in the new appearing, small window.
your objecs are now one object.
Go to "edit" and choose "plane cut".
meshmixer will supply a plane wich you can move with the navigation arrows until they JUST touch the leaves you meshmixed onto them.
Make the cut when your satisfied.
do not select "no fill" when you click accept. both other options will do.
Go to "analasys" and select "flat fill" and "auto repair all"
Now your raspberry is ready for 3D Printing.
But we want a mold ;)
i know you looked high and low, so here it is;
first thing you need is a form wich can be used to hollow your model out(substract it off-make negative-etc)
i suggest you go to "meshmix"-"primitives" and "append" a cube.
now scale, stretch, and drag the cube on top of your raspberry for measuring,
stretch till the whole half :p raspberry fits in it, then pull it out until it Nearly sticks out of the cube.
select one model at the time in the object browser, go to "edit" and select make solid one by one.
for your imported raspberry , select "accurate" in the drop-down menu, and play with the rest until you are content with the surface. then accept.
for the cube, do the same, but use standard values, and accept.
select your Raspberry(solid) in the object browser, press and hold ctrl, and then select your cube(solid)
you can unvieuw the meshes by clicking the "eye" icon next to your model names in the object browser for more clarity.
now choose"edit" and then "boolean diffrence"
if the wrong side appears, ctrl-z, & try changing the sequence of selecting Solids (first raspberry, then box)
if the result aint wanted, ctrl z, or click "decline"
and "transform" your cube or rasberry up and down until it works,
if it still doesnt, try rotating the raspberry 45° according to the box.
you should get a result similar to this:
now your solid is just one model.
you can now "cut planes" again to reduce material use in printing.
"analyze" and "fix all"
And before exporting, we are going to "reduce" the number of faces by going via "select",
selecting any part in the model by clicking on the model
and going via "edit"in the newly appeared menu, too "reduce"
in this case, you want to select "triangle budget", research the rest ;)
keep the second drop-down-menu on "shape preserving"
and click the "tri count" slider back until one fourth (1/4) of the slider.
make sure "preserve boundries" is checked and
accept. your filesize just went from +/-80.000kb to +/-7.000kb,
wich is about the max filesize you can comfortably load on a windows pc running repetier with less then 4GB Ram memory
now click "export" (left)
3D Print the mold, preferably in someting flexible or soluble, something hard wont work because of the raspberries form,
the model will not come out of a PLA or ABS hard material form. just the way it is with the raspberry i made.
you could "remesh" the raspberry before the "boolean diffrence" to smoothen the surface and fix this.
i won't, my girl just asked me if she had to "buzz like a pc too" in order for me too come to bed...
just, Print the model, or have it printed online or locally via 3D hubs or your local 3D printing store,
take 1L icecream
take 300gr red colored jam
take 3 kiwi's and squash them,
mix(spatel/handmixer) jam with the 4/5 icecream and a coffecup of whipped cream
mix(spatel/handmixer) kiwijuice with the 1/5 leftover icecream and good dot of whipped cream
leave the icream in the freezer until everything is prepared
Spatel the two color mixes in the mold, and put back in the freezer.
