My wife found this model and asked me to print it for our son's hearing aids. It prints easily and works great. The first copy was at 100% size. It was small for us since my son uses over-the-ear hearing aids and ear molds. It all fit, but it is tight. I printed a second one at 125% scale and it is perfect for our needs. Everything fits easily with room to spare. We do not use the inner sliding storage area. We told not to put batteries in with the hearing aids. This holds a very good amount of desiccant, much more than our store bought container that this will replace. Thank you for sharing this model!
