This is a modular design I created for the remote control holder contest. I have made many sizes and variations to suit any ones needs.
After printing my first batch. The fit is perfect, but a little on the snug side. I like it that way, but a little sanding and/or use will make it a smoother fit.
There are 3 sizes for the cups: 5cm tall, 8cm tall, and 10 cm tall. These can be mixed and matched to fit your storage needs. There are also 2 Wall hanger models 5cm and 8cm, but I could easily make a 10cm version if there is interest.
