Schools and colleges are under pressure to re-open after the Coronavirus lockdown temporarily shifted classes online. This can present a unique challenge for crowded classroom settings and the educational institutions will need to adapt.

We believe the Cad Crowd community can help slow the spread with open-source product designs specific to the educational environment. This virus prevention contest is a follow-up to the May challenge for the workplace and public spaces (

The latest FDA advisory suggests that COVID-19 spreads mainly from person to person, typically through respiratory droplets from coughing, sneezing, or talking. Experts indicate the risk of infection can be reduced with masks, physical distance, and barriers between individuals in spaces where groups of students gather.

The goal for this contest is to create open-source designs shared under Creative Commons that can be affordably produced with 3D printing and/or off-the-shelf components (pre-made parts, plexiglass, etc.).
The contest is open to designs that involve barriers, modular walls, or ideas that encourage social distancing in schools. Locations may include classrooms, hallways, gyms, cafeterias, libraries, etc. Specific ideas are barriers/modular walls for desks, lockers, urinals, waiting areas, cafeteria tables, one-way barriers for halls. In addition, you may want to include clips to hold the barriers in place that can be created with 3D printing or readily available components.

Refer to the contest attachment for photos to help you get started on your winning design.

Please submit your design entry with images, a neutral CAD file format (.igs, .stp, .fbx, .obj, .x3d, etc.) and a native file format if applicable (e.g. SolidWorks, Inventor, CATIA, Creo, NX, 3ds Max, etc.). Also, please upload your entry as a downloadable file onto the CAD library, so others can view and download designs -

All community members that submit a high-quality design receive 50 bonus points on the leaderboard. We’re also aiming for corporate sponsorship to increase the prize value and number of prizes for this contest.

We appreciate your participation in this challenge to help safely re-open schools by Fall.

Hi @AX.Design.PDX,

The partial barriers are probably the most simple option for creating some artificial distance. Full enclosures will difficult/expensive to install and you're probably right about issues with fire marshals.

The UVGI system is a good suggestion and there may already be good options on the market for that. The duct air purifiers is also a good idea, however, maybe it'd be difficult to retrofit old ventilation systems with a DYI air purifier. For this contest, it's probably best to focus on artificial barriers and let HVAC contractors deal with ventilation (unless you have something specific in mind).

Chat soon,

It seems like plastic barriers are preferred as a means to reduce the chance of spreading COVID19. One concern I have as a parent and a designer is how are these barriers going to be approved by a fire marshal in a classroom. It seems like some of these full enclosures could get in the way of children evacuating in case of a fire. Also I feel like we are introducing more surfaces that can hold the virus on them and students will end up sitting at those same desks. Why not encourage students to clean their area and also utilize UVGI upper room systems as well as in duct air purifiers? Reducing the particles that float in the air and settle on surfaces seems like the way that high tech industries deal with keeping areas clean and not contaminated.

Hi All,
Appreciate all the time and effort with the project. At this time, let's focus on concepts that follow along the lines of @Akash Jayanthan's work, rather than masks. There are a lot of masks on the market and this area is already well served with other design initiatives.
Enjoy your weekend!

Covid-19/Coronavirus Product Design and 3D Printing Challenge (open source designs)
With the outbreak of Coronavirus; testing, social distancing, and handwashing have helped prevent the spread of this disease. One area responsible for the further spread is frequently touched surfaces in offices, stores, and workplace areas (i.e. door handles). We believe the Cad Crowd community can help prevent the spread by creating open-source product designs for public spaces. The contest involves creating products that will be shared under a publicly downloadable open source license (Creative Commons). The goal is to develop designs that can be quickly and affordably produced with 3D printing and/or off the shelf basic components (i.e. pre-made parts that are readily available).
Animal (and other) themed kettlebells
This is a competition to design animal (and other) themed kettlebells. It is important that there are no sharp edges and no protruding elements that could cause injury or get stuck on clothing. The design will also need to allow for our logo being evident on the back of the kettlebell. Whilst the logo has been attached, the designers are free to adjust it in size, position, and proportion as they deem suitable. The size needs to be consistent with a normal sized competition kettlebell, which is easy enough for people to look up but as a rough guide: Handle Diameter: 33MM. Distance Between Handles: 123MM. Base Diameter: 140MM The actual design can be representative or a bit cartoonish, depending on the aspirations of the designers Nominated animals include: A lion, leopard, elephant, rhino (all obviously flattened down in their contours for safety), shark, eagle, dragons, snake, scorpion, crocodile, bear, wolf, Tyrannosaurus rex, Sabre toothed tiger, spider This list is a guide and designers are welcome to choose other animals or themes I do not require any primates and do not require skull designs

Custom Mouse Design
Looking for a unique computer mouse concept that can enclose a finger wearable ring inside and has a clear opening cover. The cover acts like a see-through area for the ring and can be easily opened for the retrieval of the ring. The optimal solution would have minimum parts and design of manufacturing feasibility. The cover hinge should be sturdy to support a long lifespan. - The mouse design should have ergonomic curve geometry to rest the thumb of the users. - A compact design that can house two AAA batteries and the PCB board is required. - The bottom part should have an opening to expose the optical sensor of the mouse. - No power slide switch is needed since it is provided on the ring. When the cover is open, no electronic board should be visible Approximate dimensions – L 115mm x W 66m (as compact as possible) - LED requirement - An LED indicator needs to be provided on the mouse (see the image attached with dimensions) - Battery – Should have an opening for a battery for the replacement. - Required file format -. step *Note – The base of Finger wearable ring to be in level with the base of mouse (see the image attached)
Baby wipes case
A travel baby wipes case with two snap clip mechanisms. One to open the case to reload the wipes and another on top to access the wipes. The design should be as flat, sleek and as close to dimensions as possible. Various prints will be added so design should consider how a print may be interrupted or warped. A small loop needs to be added where desired for a lanyard to attach the case to bags strollers etc. Dimensions should be as close to W:120mm H:21mm D:30mm. The design should not infringe on internal compartment for wipes so the case can be closed easily. Potential for future projects for winner.
