M5 T-Nut for 2020 aluminium profile

thingiverse

This is a little bit over-engineered m5 t-nut. Basically idea is to use cheap M5 half nut that is small enough to fit into the 2020 profile slot. You will need standard M5 HALF NUT and thin M5 washer (I used A2 stainless steel M5 half nut and 0.8mm washer). Print the part, insert M5 half nut into hex hole. Put M5 washer on top and press it until it clicks into place (use pliers). After that it will never fall apart until you break it. The plastic part prints perfectly without any support. The quality not important (I printed with 0.2mm slicing). The plastic part play only guidance role and all the holding role taken by the m5 nut with the washer. UPDATE: some 2020 profiles has smaller slot depth, so updated it to fit with thin washer (0.8mm).
