If it seems too little heat two units could be installed these mini heaters (only 50W) will heat up faster.

To install, cut one of the acrylic panels about 18cm

Use thermal insulation fabric in the direct hot air area and internal Top printer to protect the electronics and not lose heat inside the enclosure. It is advisable to add extra ventilation to the electronics area.

I use temperature sensor inside the enclosure with this temperature controller (24V):
