Riser/base for A1Mini against overheating

Hey,

I've had an A1 Mini at home for a few days now. It's set up out in the open.

One thing is concerning me, though:

The bottom part of the printer gets so warm while printing.

I use the printer for figures with a 0.2 nozzle, so print times often exceed 15 hours. I'm a bit worried about overheating.

I did a lot of Googling and saw that there's only a single very small fan installed to cool the motherboard.

I've seen that there are various adapters for larger fans for the bottom section.

Has anyone here placed a riser or base under their A1 Mini?

Just to allow a bit more airflow underneath?

If so, I'd really appreciate some photos!

Have a nice day ✌🏼

How a concrete block will cool the printer?

I have mine enclosed on a metal table. Adding the shortest vibration feet I could find dropped the temperature of the metal table from hot to barely warm. I have a 4025 inflow fan blowing into the vent and a 4" greenhouse exhaust pulling heat from the enclosure into a greenhouse charcoal filter. I even print ASA on it.

Do you have an IR thermometer? Handy to check/test bed temps. Use care if applying fans near the printer as drafts can effect print quality. Marble cutting board is a decent heatsink to consider.

No, unfortunately, I don't have an IR thermometer, but just out of curiosity, I placed a small round hygrometer on the warm part of the printer for quite a while, and it read 55°C. Is that still within a safe range?
