This repository is a collection of some of the designs I created with OpenSCAD.
For each one of the projects you will find the .scad source file(s), the .stl 3d model(s), and a .gif image to quickly visualize the result.
A Makefile is also included, which - assuming to work on project/scad/object.scad - can be used as follows:
make project/scad/object.png-> create a PNG of the objectmake project/scad/object.gif-> create a GIF of the objectmake project/scad/object.stl-> create the STL of the object
Here is a list of the projects:
This model is a modular, fully 3d-printable, flexible tentacle that can be controlled through two servomotors.
For convenience, the tentacle is split into multiple parts so that it can be extended as much as desired by simply adding new sections. Just be sure to give an opposite orientation to two consecutive springs, which are used to provide flexibility to a fully-PLA structure.
Two servomotors are able to move the tentacle horizontally and vertically at the same time, thanks to a system of nylon wires and adjustable pulleys. Their housing can be seen at the beginning of the tentacle.
The overall design has been developed with a focus on compactness and lightness, since the final goal of the project was to develop a wearable robot.
You can take a closer look at the SCAD sources and the STL models.
These models are a variety of small and simple building blocks to create more complex designs.
They basically include planes and various kinds of joints, and everything is well-parametrized so that they can be created with the desired size. All the parts have holes since they are meant to be mounted together through M3 bolts.
Lastly, there are also some models that allow mounting lcd displays, motors, and wheels. This is because the project has been created with the goal of having a simple library to prototype the chassis for a modular mobile robot.

This model is a case designed to quickly prototype with two servomotors moving along two different axes.
In the base there is space for two breadboards and a slot for a usb cable connected to an ESP32. In the vertical plates there are two slots for the servomotors and two holes for leds, useful to provide information about the current operating status. Everything is kept together through four M3 bolts in the base.
The project is intended to just simplify the placement of the electronic components, while cables and jumpers are organized in a tidy way inside the enclosure.

This model is the accurate replica of a small part that broke and couldn't be find on sale.
In particular, it is one of the two feet of a signal generator. Without it the instrument couldn't properly stand upright. There's nothing particular to point out, I just took some measurements of the broken part and modeled a new one. Easy fix.

This model is an upgrade I created for my 3d printer to improve the sliding on the filament spool.
In fact, as the filament is pulled by the extruder, the spool slowly starts rotating to unroll itself. While this is not a problem per se because everything works as expected, the sliding of the spool is not optimal and it unrolls in jerky movements. The resulting noise is also quite annoying (ok, maybe it is negligible compared with the fan noise, but still).
So I came up with this part that can be mounted on the already exixting structure of the 3d printer. It is thought to be integrated with a small ball bearing thanks to a snap-fit system, which allows the filament spool to unroll itself very smoothly and in a silent way.
