3D  Printed Manipulatives

With the advent of 3D printing, it's now easy to design and make manipulatives and other teaching aids.  On this page you'll find tutorials on designing and printing your first thing, STL files for the things that I've designed, and other helpful links. 
For the files below which use magnets, they are all designed to accept 8x3 mm rare earth magnets.  The best price I've found (about $0.10/magnet if you buy in quantity - if you can stomach a long shipping time...) is here:

3D Printing (STL) Files

1. Physics Vector Arrows set

A set of vector arrows with labels.  All parts have voids for 8x3 mm neodymium magnets.  Vector labels can be attached directly to board or onto labels.

Includes: 
  • 3 Vector Arrows (150 mm, 200 mm, 250 mm)
  • 14 Labels (F1, F2, Fc, Fe, Ff, Fg, Fm, FN, FNet, Ft, v, x, y, E)

4. VSEPR Arrows for molecular models

A clip on bond dipole arrow for ball and stick models.  Our are Ward's (82-1108) but also works with wooden VWR set.  

Can be easily scaled larger or smaller to accommodate different sized dowels.
