Churros huecos (rellenos) trefilador personalizable / Customizable cutter hollow (filled) churros

thingiverse

This is a customizable tip for churro/cookie machines that function as plungers, but it should also work with pastry bags (fully customizable, using OpenSCAD code). It allows the creation of hollowed churros that can be filled with "dulce de leche," pastry cream or any marmalade. The source file (perfiles1.scad) has two ready-to-use modules and the corresponding STL: * hueco1: Based on existing models, it features a plug in the center (which makes the hole), supported by three rods. * hueco2: My own design, the plug in the center is floating; also supported by rods, but they are floating. I tested with 25% infill and it works great. And, there's estrella1() which creates a common churro tip with no hollow. Also, there are ciego() and abierto() modules (which make closed and open tips respectively), both can be used to create custom tips. If you're interested in customizing the sizes: • D0: Outer diameter. • D1: From D0 to D1, the height is H0 and is flat. • D2: Inner diameter. From D1 to D2, the height increases from H0 to H1. • D3 and D4: diameters for star. • D5 and D6: diameters for plug (D6 makes a hollow in the plug, so it becomes a ring). • H2: Height of cylinder (plug) in the center. • H3: Height of cylinder which is connected to rod in hueco2(). • N0: Number of points of star. • NR: Number of rods. • L0: Width of points of star. Note: Keep in mind that crude 3D prints are not recommended for food preparation.
