Description
Are you a teacher looking for geometric manipulatives for math class? A crafter needing perfectly sized stencils? Or maybe you just need to generate a bunch of blank custom keychains? This fully parametric OpenSCAD generator instantly creates 15 different mathematically perfect shapes at any dimension you require.
MembershipEducational toys and custom crafting stencils are bestsellers on Etsy and at local craft fairs. While this basic generator is freely available, joining my Commercial Membership for only €4.99/mo gives you full commercial rights to sell physical prints of this model, AND unlocks commercial rights to ALL my other premium generators!
To provide the absolute fastest rendering performance, this model generates 2D vectors and linearly extrudes them into 3D manifolds, avoiding slow 3D booleans whenever possible.
The shapes are dynamically bounded using mathematical min and max limits. For example, if the user inputs a corner radius larger than the shape itself, the algorithm dynamically clamps the radius to prevent the geometry from collapsing or inverting inside the slicer. The massive All Shapes layout is generated using a nested looping array that calculates a localized offset grid while reading the individual properties of all 15 different profiles simultaneously.
I love seeing your colorful classroom setups and custom keychains. Please upload a photo of your make!
