iQair health pro 250 better rollers/casters

The included casters were bent and not suitable for parquet and tiles, so it was a good idea to use standard casters for office chairs. I constructed a bracket that fit into the recess braces on the bottom and screwed there, as it was before with the original.
The holders are actually well clamped, but can be fixed with screws. 4x M5x20mm screw & M5 nut.
Printed in PETG, they hold up well.

I chose them because the black sleeves were included.

I would like to swap the bolt hole for a receptacle for a M5 nut, unfortunately I no longer have access to Inventor. Otherwise it is difficult to hold the nut. I will attach the file though in case someone wants to swap it.
