This is Prusa Bear MK3S MINI, it is an Ultra Upgrade and it worth the research, challenge and design to have a mini workhorse.
Update:
Use the firmware 4.3.3 or later and go to Settings → HW Setup click and hold up until new menu appears then go to Extruder steps and set it to 140 save and restart. with this the pear.ch.ini profile will work correctly. Enjoy
Here are the pictures shown.
It works better than a MK3S and way better than Prusa MINI.
Buddy Board, Heated Bed, Minda, Powder Coated are original Prusa from Prusa Research, hotend E3d Original V6 and the rest of it it is steppers and aluminium extrusions are parts they were spare parts staying there so we used all of it.
