Parametric Well Plate, With Negative
by naroom, published
Well plates, for your experimental delight! Make as many wells as you want. The well radius, volume, and spacing are all adjustable.
Most people are going to want the "positive" well plates. Just download the openSCAD "positive" file, tweak parameters to fit your application, and go! Sample STLs are provided too.
The "negative" files are for people who want to make a mold of this. For my application, I needed a set of silicone well plates. So, I printed the "negative" version on my 3D printer and poured silicone into it. The result was a silicone "positive" - a set of well plates in silicone. I used these silicone well plates to compare different kinds of cast polyurethane plastics.
It's a good idea to print these with 100% infill if you plan to put liquid in them. Every time I've tried going cheaper on it, it's come back to bite me later :)
PLA worked better than ABS for me on this print.
