Spool wall support filament

I designed this spool support for 3D Hero filament https://www.amazon.es/gp/product/B07CPW7DRX/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1, for wall mounting.
It is necessary a bearing model 608-2RS 608RS x 2 units. https://www.banggood.com/10pcs-8x22x7mm-Deep-Groove-Miniature-Bearing-Sealing-608-2RS-608RS-Deep-Groove-Ball-Bearing-p-1052876.html?rmmds=myorder&cur_warehouse=CN
I attached the solidworks files if you want to modify anything. But if you need anther type of file I can convert it and upload.

I did a filament guide for the spool support, there is not necessary screws or anything only insert into holes of the support and nothing else. In my case I was having problems when I started a new filament because the filament take out of the spool and then began a jam.
It is a improvable part and I accept any change in it.
