This is made by a 3D printer out of ABS plastic. We found ABS to be more durable than other 3D printing materials, such as PLA. ABS is BPA free plastic that is food contact safe and used in everyday life from luggage to helmets to kid's building bricks. Another advantage of ABS is, unlike PLA, it can withstand higher temperatures so you don’t have to worry about leaving it in your car on a hot summer’s day. Although ABS can withstand higher temperatures we do not recommend putting it in the dishwasher. Instead you can wash it in the sink with soap and hot water or use isopropyl alcohol to clean. This model is based of a Public Domain model made by MakerWorld user Feprint3d. This model has then been heavily modified and customised to be used as a scent training device.
