Buy in your local hardware store:
M10*400mm Threaded Rods 2 1$
M3*8mm Bolts 11 0.5$ Also you can buy it online
M3*20 Bolts 10 0.5$
M3*30 Bolts 8 0.5$
M3 Nuts 22 0.5$
M10 Nuts 8 0.5$
Buy it online:
Linear Shafts 8mm*400mm 2 8$ Or reuse from old printers, scanners, etc.
Linear Shafts 8mm*300mm 2 6$
Linear Shaft 6mm*200mm 1 1$ You will need to cut 2 pieces from it.
LM6UU Bearings 2 1$ Or print plastic bushings with PLA plastic
LM8UU Bearings 8 4$

GT2 Belt 2 m. 2$
Electronics:
Arduino + CNC Shield + A4988 Drivers 1 9$
Nema 17 Stepper Motors 2 15$
28BYJ-48 12V Stepper Motor 1 1.5$ Better get 2 of them, they can came damaged from factory
Wiring Kit 1 1$
Power Source 12V 4A 1 4$ Search for it in your electronics scrap
Total estimated price: 62$ If, when you press the link, price is higher, try to search similar product on Aliexpress by yourself.
Without LM bearings, power supply and linear shafts (reuse old ones from printers or buy aluminium round strips in hardware store. don't use metal bearings on aluminium strips) - 38$. Also you can always find a bit cheaper parts on sale on AliExpress.

Est. plastic use Est. print time Est. electricity use Est. price
308 g. (102 m.) 24:17 4.86kWt/h 6.76$
Estimated with this data: PLA plastic with density 1.25 and price 20$ per kg, 0.4mm nozzle, 50mm/sec print speed, 50% infill, 3D printer consumes 200W, 0.12$ per kWt/h
249 g. (102 m.) 24:17 4.13kWt/h 2.30$
Estimated with this data: ABS plastic with density 1.01 and price 7.49$ per kg, 0.4mm nozzle, 50mm/sec print speed, 50% infill, 3D printer consumes 170W, 0.11$ per kWt/h. This estimation real and I placed it here to show you, how cheap can be 3D printing if you going to buy filament in right places during Black Friday and print with ABS (yes, it is cheaper, because ABS has more meters in one roll). :)
