I recently bought this Inventum heated blanket which came without a nice holder for the controller. So, I fired up TinkerCad, smashed some blocks together, et voilá, the Inventum Heated Blanked Controller Holder (IHBCH for short) was born.

And naturally, I will share it with the world for free.

Hope you can make use of it, and if you like it, please let me know.
