I got another flawless, perfectly produced PCB by Eurocircuits. This is Revision A of the input panel board I published in the last post. There are only minor changes in the silkscreen and a little bit larger rings around the holes for the LED. Eurocircuits is not the cheapest board prototyping service, but in my…
Input Panel – Request for Comments
I am currently working on the input panel board for the pet-feeding device. You are invited to review the board and send me your comments or suggestions via this page, Twitter or email. About the Input Panel The input panel is directly connected to the controller and contains the rotary encoder for the input and…
Let’s Print a Cat/Pet Feeding Device (Part 5)
In the fifth part of this series, we print the turntable and talk about the back panel of the enclosure. If you missed one of the previous parts, visit the overview page to access them. The Files You will find all required files for the prints in the GitHub repository: About the Turntable Before we…
Let’s Print a Cat/Pet Feeding Device (Part 4)
This is the fourth part of the series. In this part we insert the insets in the previously printed parts, print the lids and talk about the front panel. If you missed one of the previous parts, visit the overview page to access them. The Files You will find all required files for the prints…
Box in 500 Sizes with Smileys
I just published another set of 500 boxes. The new set has smiley faces as decorations. As with the heart and lines set, the box comes in 500 sizes with two different lids for each. Part Numbering To choose the right box, you need to know the inner dimensions. There is the width (x), depth…
Box with Random Line Pattern
Because the box with the heart pattern worked out great, I tried something more complex this time. The new set features a random line pattern. All four sides of a box have the same, but each box has its own random pattern. Like the previous set, I generated 500 different sizes for the box with…
Let’s Print a Cat/Pet Feeding Device (Part 3)
In this third part of the series, we print three panels for the enclosure and the rotary platform. If you missed the first or second part, visit the overview page to access them. The Files You will find all required files for the following prints in the GitHub repository: The Left Side File: LR2051-404A.stl Material: PETG…
Box with Heart in 500 Sizes
I tried something new with parametric design. 😄 Today I publish the first batch of heart decorated boxes for 3D-print in 500 different sizes. The sizes start from 35mm up to 120mm in small steps, so you can choose a box in the perfect size for you. The print above is a very small one,…
Let’s Print a Cat/Pet Feeding Device (Part 2)
In this part, we assemble the gearbox. It is the second part of this series. If you missed the first one, read it here. Requirements for this Part You will need the printed objects from the previous post: LR2051-101B.stl LR2051-102B.stl LR2051-103B.stl LR2051-104B.stl LR2051-105B.stl LR2051-107B.stl LR2051-108B.stl LR2051-111B.stl LR2051-112B.stl LR2051-121.stl LR2051-122.stl LR2051-123.stl LR2051-124.stl LR2051-401A.stl Also, these components:…
Electronics Invisibly Embedded in 3D Prints
After successfully embedding magnets, I started experimenting embedding whole PCB boards into prints. I am sure, this is no new idea, but I found it very interesting. From the outside, the printed object looks solid and there is no trace of the board visible. The board and all electronics are perfectly sealed in the part….
