One of the first mods I made for my monoprice mini delta was to download some feet that raised the mpmd a bit higher, improving the air flow for the cooling fan lowering the noise level.
Now the printer is still bringing quite a bit vibration to the table, so I looked into replacing those feet with some tpu prints, but I liked the red PLA feet so much, and had only black TPU that I ended up making shoes for the feet, so i could have a flex layer below them, rather than full-flex-feet.
