Computer Feet Riser

I made this for my NR200P case so that there could be a bit more airflow under the case but these can be used for really any computer/thing that has those 4 point feet. These are 20mm tall, enough for airflow while keeping my computer shorter than me.The inside base is 24mm x 24mm and its pretty strong. If you want you can increase the infill but I found that at 25% its enough for me.I recommend using supports for that bottom hole, I designed it so that you could put a piece of rubber to stop the feet from sliding.Though I didn't need to do that as the weight was enough, but it's up to you. Please let me know if I need to make any changes or if you want one designed specifically for your needs :)
