The dimension of the phone slot is 79X9mm. However, I printed this and it did nothing to amplify sound, and in fact just muffled it.

Still printing, but it works without support!!! Later I upload the pictures!

Did you print it in the original file orientation or did you rotate or move it to get it to print without supports?

I rotated it bottoms down whitout supports. It is almost perfect, fits well. There is a little problem with does not botter me. Oneplus 5T fots perfect

Thanks for sharing the pics. I'll try it with the rotations you did. :-)

hi, what s the dimension for the phone slot? planning to print this for my granddad he have hard time of hearing, I need a 78mm x 10mm for the length and width of the phone slot. ty

Love it. I am super happy with this simple design. I printed with a brim and supports. Just to make sure. I would like to see this same thing for watching movies. Horizontal version!!!

Wondering if this will print without supports, it looks like it just might? Has anyone printed this successfully without supports?

What kind of phone is it for?

You can use it for almost all types of phones.
Sorry for the delay in the response.

What is the best way to remove the supports? I'm having a heck of a time. This is my first time printing something that had any. Thanks!

I usually remove the supports with a cutter.

Works goot with the Honor 8 :-)


But the supports are messy to remove....

What supports did you give this? buildplates? or just supports everywhere?

HI! 5%, lines at 0.2mm distance.

where located speaker in your phone ?

Most phones have the speakers at the bottom. Therefore the sound enters directly through the gap and is amplified in the parabola.

Thanks for the design. Works well with my Pixel (non-XL).

Loved the simplicity of the product.
