kenanjo The frame is very straight forward to build compared to the ones with plates. No measuring at all, just put the bolts in. But if like me the excitement took over you then have to then take them out again, insert a T nut, put the bolt in, repeat many time. If you really need instructions, Search for "FYSETC bear" to find more detail to build the frame. Avoid the multiple build by reading the bear assembly from Gregason at least 3 times and note where all the t nuts go before you build the frame.

kenanjo look on github.com for gregsaun prusa_i3_bear_upgrade plus search for "FYSETC bear" to find more detail to build the frame as the frame is not the same build method as the official bear kit

kenanjo as it comes it uses 1.75mm

kenanjo most of the kit is from FYSTEC. There are many sellers for all parts since it is open technology. You could even go to the OEM that Prusa uses such as E3d for extruder parts. In my case I did buy a spare E3d extruder and other hot end parts. They are no better and possibly worse than the parts in the kit.
