Topsie, I have remixed some parts to use 10mm leadscrew and to use 40x40 in place of 20 x40 on the side rails.  Do you have anywhere or any plans for somewhere that I can upload the files to so that others may use them?

Topsie, Love this design! I have been going through and printing various files for the Heavy version, and would like to modify some of the parts for the Arduino case as well as some other parts to fit my needs, would you be able to send me the STEP files for Fusion 360? My plan is to remix the Arduino case to fit slightly larger cooling fans and insert a raspberry pi to allow for wireless control, and edit other parts to allow addition of webcams and stop sensors.

Yes i will share my step file soon

Can't wait to see I've got some ideas. First I need finish build the original before I start playing with the design
