About this 3D model
Arduino UNO R3 enclosure. There is a 6mm space between the bottom of the circuit board and the bottom of the enclosure. The elephant foot compensation is 0.35 (untested. I used the default elephant foot compensation of 0.15, there is elephant foot, but it doesn't affect much, so I didn't care). There is no top cover. The left and right spaces of the power port opening in the sldprt file have been expanded. The video is published on Bilibili: BV1vb4y1A7ab. How to use: Print → Put the circuit board into the enclosure → Heat and melt the thin pillars (need to melt at least 3, a total of 4).
