This is a printable plastic plate used to mount an aluminum angle iron to the Trinus X carraige so as to be able to mount a Flexion Extruder.
Anyone who owns a Kodama Trinus eventually gets fed up with the stock extruder. Although reasonably capable, it's enclosed design encourages heat creep and clogging. Many owners have adapted the E3D extruder. I decided I would prefer the Flexion for its unparalleled ability to print flexible filaments.
The pictures are accurate if a bit misleading. They show an earlier iteration with a longer aluminum bracket. I found the longer bracket used too much z axis height, so I shortened it. The principals and directions are the same, but your finished product will look slightly different. There is also a cooling fan mount not shown, which I added later. The file is here for that as well. The fan mount is screwed into the X axis plate using longer 3mm screws to go through the fan mount and then the extruder mounting plate and into the two threaded holes on the top of the X carraige.
To use this plate you will also need a two inch wide, 2" x 2" aluminum angle. On one side of the angle you will need to drill two 4mm holes to allow two M3 screws into the tapped mounting holes on the bottom of the cold block. You will also need to drill a 10 mm hole to allow the throat through the aluminum angle.
The back of the plastic plate has countersunk holes for tapered head 6 mm M3 screws. You will need to drill corresponding holes into the other side of the the aluminum angle, and thread those holes with an M3 .5 mm tap.
