Casper, the mid-size delta printer

This is Casper. It's my very own mid-size delta 3D printer. Dimensions are 280x265x520mm, printable diameter is 160mm and printable height is about 200mm. Casper is driven with Nema14 steppers (including extruder, geared of course), has E3D v6 clone hotend with 0,3mm nozzle, cooling with 30x30 and 5015 fans. There is no heated bed, only ordinary glass as print surface, so printing is possible from PLA only. Using ANET mainboard with small hardware modification for calibration probe (mechanical contact from old CD drive). Endstops are small microswitches, from old computer mouse. Because of no heated bed, the power supply 12V/5A is sufficient. Extruder using MK8 feeder, small bearing 624ZZ and gear ratio 1:4,3. Diagonal arm is made from M3 threaded rod and ball joints. There are printed LM8UU bearings. All metal parts are aluminum tube 8mm diameter and aluminum profile 10x10x1mm

All printed parts are printed mostly from PETG-CF except cable holders, bearings, spool holder, bed holder
