Belt Tensioner for Ender2

remix of fessyFOO´s Belt Tensioner for Creality Ender2 X (20x20 profile) and Y-axis (20x40 profile)

The parts are meant to be used with the original pulleys.

The pulleys are a 2part design with 8mm ID and an overallwidth of 10mm.
Insert the spacer (Spacer_-_ID5_OD8_L10) and you end up with a pulley for 5mm axis.
I took some Ikea "cabinet joiner" with 5MM OD and a length of ~24mm, shortened them to 20mm and used them as axis.
The puller is designed accordingly: 5(mm)a(xis)8(mm)b(earing)1
