I suggest using my universal print files (gcodes) instead of slicing.

Upload the gcodes on an SD card and insert it in any printer. Launch the gcode from the printer interface, ignore warnings and proceed. Adjust temperature and fan speed once the print starts to fit your filament needs

Printer requirements for the gcodes: 0.6mm nozzle and at least 180x180mm buildplate

Roy draws air from the sides and the bottom. The air drawn from the bottom is filtered by activated carbon, which removes odours and gases, the air drawn from the sides is filtered by Hepa Filter, which removes dust and allergens. Overall, the air in a room is filtered by both activated carbon and Hepa filter.

Roy works with 120mm fans. The frame of the fan has to be removed by cutting with pliers. Then the fan is attached to the cap with thick double-sided tape.
The best fan is UpHere, which is smaller then usual 120mm fans, that is why there is a custom "uphere" version of Roy. Use the "generic" version for other fans. If you choose a USB fan, you can add a "usb fan speed controller" (Google it) to adjust and increase USB fan speed.

Cut 3 Roy filters from 1 30x60cm Hepa filter sheet. Google "Frameless hepa filter" to find it

Use 3-5mm granular activated carbon
