T4 Mini 250 arm, modded for UP printer...

you can not turn off 'support' on my UP printer....and it was impossible to remove from inside the arm, and running wires inside just did not work.....

so I widened, the 'ibeam' till no support was laid....

my printer printed the motor cup as 2x 1mm layers that were not connected, thus very flexy ....I added a 'bulbous' section to the outside of the motor cup, so now it prints in one piece...cup is now 10x stronger on my printer, wider Ibeam means stronger arm as well....total weight incr
