Inky Pi 3d delta printer

This is my 3d Delta printer named inky Pi. it is a modified version of delta pi. Using 10mm balls and N52 magnets to hold the rods and effector plate in position.
software used is repitier firmware on Adruino and ramps controllers.
The top and bottom bases are 18mm MDF, with a laminate floor board connecting them vertically, this is used to mount the power supply, the reel and the extruder on.
The vertical tubes are 20mm square stainless steel. I left these at 1m long giving me a 550mm print height.
The carriages have 8 off 623ZZ ball Bearings mounted on 3mm stainless cap heads.
The link rods are 4mm dia carbon fibre with the rod ends bonded on and are 270mm long.
My machine has been running now for over 12 months and gives excellent results.
