This is my small 3D printer. It is not mini (A little bit smaller, than standard Prusa). No parts for laser cutting. Basic things You need to have in mind, if You want to make it:Printer in action:
6 mm smoth rods(relatively LM6uu bearings), M5 threaded rods for Z(2x 20mm M5 nuts), PC PSU 350W, E3DV5 (reworked) clone, Mega2560+RAMPs 1.4, Nema17 motors and Geeetech 152x152mm heated bed. My build size is XYZ 110x140x90mm. Z can be extended to 100-105 mm. X can be extended to 140 mm, if You want to lose 3 point bed leveling and to rework Y holder for heatbed.
All files to make it can be found at:
