I picked up a shelf instead of making my own shelf to put an air purifier on it in my 3D printing lab. The shelf indicated to be able to support 20lb, the air purifier is 12lbs. I put up the shelf, and I did not feel comfortable with the brackets it came with as they were flexing significantly under the weight of the air purifier. So I made replacement shelf brackets. Now the shelf is very secure.

This is the shelf it will match: https://www.amazon.com/gp/product/B07VYGD6JH/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1

Custom DIY

No

0.24mm layer height

25%

Nothing special, I used my printer in idex mode, so I printed both of the brackets at the same time.

Remove from bed and secure to shelf/wall and use

I designed it to be printable with no supports with various settings. It will match the base hole pattern of the shelf
