# Possible with WSF/RSF? (3mm sphere with 1.5mm hole through it)

Possible with WSF/RSF? (3mm sphere with 1.5mm hole through it) [message #53650] Wed, 05 September 2012 18:56 UTC
Um... basically: a really small bead.

I am curious because I've been into hand-made crafts for the past half-year and for some unknown reason I cannot find any white or red 3mm beads that aren't pearlescent or don't have large enough holes. I am considering Shapeways as a solution to my bead dilemma, but I'd like to know if these dimensions are possible first.

I also suck at modeling and have no clue how to get things to scale. Attached is an STL file of a single bead if anyone wants to take a look at it.

Thanks for looking!

Well if your doing wsf, your walls have to me at least .7mm. But your min bounding box is 7.5mm (x+y+z), but if your bead has a diameter of 3mm, it'd only have to be at least 1.5mm tall. So yes it should be printable as long as you follow these rules.

Thanks for the input! I guess I'll order a sample and see how it goes from there.

3mm diameter = 3mm tall

A 3mm diameter sphere will have a bounding box of 3 x 3 x 3 mm = 3+3+3 = 9mm, so is good for the specs, however a bead with a hole will have one axis shy of 3mm.

An alternative to buying in one bead of those dimension is to have many beads on a string or in a box - the string/box is part of the model file too - this will help keep the individual bead price down too. Looking at the model file, a 1.27mm dia hole may be a bit small for a string without fusing the (0.7mm) string to the beads, but putting a hundred or so in a box/cage will keep the unit price down.
