I need to crush three pills every morning and designed this pair for the job. Three fairly small pills which I do in one go.
Designed in MOI.
Made on a Robox in Robox ABS. (As you can see I've not yet mastered the art of a good surface finish).
Although I've made these in ABS I recommend using PLA as it is a harder material and, I think, more suitable for this application.
Having used this for a while I have some recommendations on how to best use it:
- Press down hard to break the pills into smaller pieces.
- Then while rocking the pestle forwards and backwards, rotate the mortar.
Works surprisingly effectively - or so it seems to me!
After some weeks using this I concluded that the pestle could be a little taller and that more clearance between the sides of the mortar and the pestle would give more room for the 'pill powder'. The updated design is pestle 01.stl.
The distance between the deepest part of the mortar (the bowl) and the underside of the base is 3.2mm so I suggest that you set your wall section top and bottom at 1.6mm - and hence use a 0.2mm layer height.
I used the same settings for the pestle.
