1/2 inch conduit pipes 4x10ft
All sizes are for 350mm 8mm rods which will give you a bed size of 250x250mm.
To use different rods add/subtract length difference of rods from horizontal pipe sizes.

For new 500mm+ upgrade of Piper 2:
For 350mm rods, bed size is 23mm smaller on Y and 13mm smaller on X due to larger carriages. So 350mm rods will produce bed size 237x227mm. If you want bed size of 500x500mm you will need rods at least 350+(500-237)=613mm on X and 350+(500-227)=623mm on Y. Then to calculate the required pipes add delta 613-350=263mm to all pipes along X and add 623-350=273mm to all pipes along Y.
Pipe Sizes are the same based on 350mm length of rods with exception of:
Pipe location Pipe size for 350mm guiding rods Quantity
All frame pipes along X except back bottom pipe 514mm 3
Frame back bottom pipe along X 520mm 1
Gantry for motor mounts 419mm 1
Gantry for idlers 419mm 1
Bed support 511mm 2
There is also small 2mm difference for UK version for frame pipes along Y axis which may be ignored (frame pipes for 500mm+ version along Y axis are 2mm longer for UK version)
