Explore rapid prototyping for 3d printed product design, with multiple drafts—measurements, threading, and leash mechanisms—as you transform a pet into a poop bag dispenser.
Learn to configure Blender for 3D print design by setting your printer volume in millimeters, linking your 3D printer inside Blender, and saving startup presets for repeatable 3D printing workflows.
Blender UI overview introduces the Blender user interface, layouts, and the 3D viewport. Learn to navigate modeling, sculpting, UV editing, shading, animation, and the 3D print toolbox for printing-ready designs.
Sketch out ideas quickly to prototype a pet product, exploring hooks, latches, leash space, and playful concepts, then translate sketches into Blender using grease pencil.
Capture multiple dog poses from front, profile, top, and lying down using phone videos to create reference images in Blender for accurate sculpting in a pet product design.
Measure height, width, radius, leash width, and thickness with calipers or a ruler in millimeters. Record these dimensions to build a precisely scaled cylinder in Blender for the pet product.
Open Blender, create a 60 mm high, 30 mm wide poop roll cylinder and a 26 mm leash, then save drafts and organize into a collection for later use.
Add reference photos of the dog from front and side views to guide the base mesh and block out the head shape.
Block the dog's head by creating a base mesh, shaping it with extrusion and scaling in wireframe, and using auto mirror for symmetry along x axis, guided by reference photos.
Block the dog’s jaw and ears in Blender for a pet product, using loop cuts, proportional editing, extrude and transform operations, guided by photo references.
Block the neck and add modifiers to shape a dog head in Blender, aligning to a 45-degree angle and applying mirror, multires, and solidify for a thin shell.
Develop a 3D printed dog head with a mouth hole sized to a 22 mm thumb measurement, using Blender techniques to scale, rotate, and refine the jaw and neck.
Add leash clips to the dog head in Blender, refining ears and neck for a printable 3d print using booleans, mirror, and proportional editing.
Design a screw-on bolt collar for a dog product in blender using the bolt factory add-on, adjusting head height, shank diameter, thread length, and pitch for 3d printing.
Learn to model a nut for a bolt in Blender, adjusting major and minor thread dimensions, tolerances, and alignment with a dog head to ensure 3D printing compatibility.
Use box booleans to cut collar parts for a snug fit, then clean up and make manifolds with the 3d print toolbox, including bolt base and threads.
Create a boolean hole in the dog head to host the poop roll, fine-tune size for clearance from teeth, and troubleshoot booleans using see-through mode and Blender options.
Design a poop loop in Blender to hold a dog bag on the neck nut, using a torus, a knot reference, and boolean cuts for a secure, printable accessory.
Design bottom and top spikes in Blender to securely hold a poop roll on the base for 3D printing, using precise diameter measurements, alignment, and boolean joins.
In Blender, adjust a dog head mesh for 3D printing by analyzing overhangs at 45 degrees in real time and shaping the geometry to print with no supports or rafts.
Learn how to add and orient text on a base in Blender, convert the text to a mesh, apply a solidify modifier, and perform a boolean cut for 3D printing.
Prep the dog mesh for sculpting by applying the mirror modifier, fixing spikes, adjusting booleans, and lowering poly count; set up reference photos and matte caps for sculpting.
Use broad sculpting and elastic deform to block in the dog head, align ears and eyebrows, refine the jaw, and plan eye placement while checking with see-through and wireframe views.
Learn to add mid-level sculpting details to a dog head in Blender, placing eyeballs, refining with mirror, booleans, and multiresolution sculpting for a pet product prototype.
Export the dog head design for 3d printing by refining the leash, verifying booleans, and exporting the bolt base as an stl file.
Learn to slice a dog base and head in prusaslicer 2.3.0, set nozzle to 210 and bed to 60, adjust infill and shells, apply supports, export gcode, and test print.
Design a pet product in Blender for 3D printing and illustrate a final 3D print timelapse, highlighting workflow from modeling to printing.
Review and refine a 3d printed doggy poop bag dispenser through prints, adjusting bag hole sizing, leash clip grip, and top spike decisions to achieve no raft, no supports printing.
