StepTec3D

Hi this is my attempt at a 3D printer size 220mm x 270mm x 300mm
The PLA printed bearings run directly on the 2020 aluminium extrusion, They are fixed onto 30mm x 30mm aluminium box section and run very smoothly after some bedding in. So far after 60 prints they are showing no sign of wear however I have already printed a new set.
