Following conversations with occupational therapists at St James Hospital Dublin, our group decided to concentrate on creation of devices to aid in daily assisted living. Many people around the world suffer from age degenerative diseases or other disabilities that make common tasks difficult, whilst novel medical devices exist to help with such tasks many are incredibly high cost due not to material costs but to low sales volumes and the need for commercial profit. By making these devices open source 3D printable models we hope to make them more accessible to those in need.

Furthermore, when visiting the occupational therapy department we identified some diagnostic devices that could easily be 3D printed. The Goniometer and the Discriminator we developed are close replicas of existing devices that are highly priced for purchase from medical device suppliers. High costs means hospitals do not stock many of either device, hence they must be shared between large teams of staff. Both devices are small simple items easily misplaced or broken leading to much frustration and at times delay in diagnosis of patients. Our 3D prints mean all members of staff could be supplied with a personal device with minimal budget requirement.

Separate from our work with occupational therapists we have also developed a clubfoot corrector brace or “othosis”. Clubfoot is a common birth abnormality in which the foot and ankle are twisted due to the ligaments and tendons being too tight. A simple way to correct this deformity is the “Ponseti Method” in which the child’s legs are incrementally forced to re-shape to the correct position. In many developing countries the braces for this procedure are not commonly available leading to many patients going untreated and reaching adulthood with an untreated debilitating disability. With our open source model we hope to make the procedure more readily available for all.


Mug Handle

This handle allows people with decreased fine motor function to continue using their collection of mugs by providing a chunky easy to grasp handle. Printing at a cost of approximately €8 this handle is far cheaper than the commercial equivalent that costs €22. The shared model is for mugs of 79 to 85mm diameter (most common sizes) but can easily be scaled to meet any requirements.


Weekly Pill Box

Commonly used worldwide to keep track of medication on complex schedule. A typical 7 day pill box can be purchased for around €10, our hingeless 1 piece print can be created for approximately €4.

Tablet Cutter

Complimenting the pill box this tablet cutter allows large tablets to be cut into manageable pieces, removing choking risk and often daily source of stress.



A print cost of €1.35 compared with a purchase cost of >€25, this design should ease the pressure on hospital budgets for small devices. Just print the part and the pdf then use PVA to align the dial to the main plate.



Another cost saving opportunity for hospital departments, this print plus the nails required comes in at less than €5 a set. And that includes plenty of spare nails for DIY too!


Club Foot Corrector

At approxinately 50 hours this is a long print as each piece must be printed individually if using standard hobbyist printers such as the Ultimaker 2. However, the total cost is <€22 compared with €190 for a commercial device. This open source model makes the Ponseti procedure both easily available and affordable for all facilities across the world.
