All models are in a single file. All use m3 screws (length depens on how many keys you are using) and m3 heat set inserts (either 4 mm diameter 4 mm length or voron sized 5 mm diameter, 4 mm length).
Everything is in 1 file, so you only need to download the one that's the right file format and heat set insert size for you.
Files are available as m3f and stl.
