AMS 2Pro Buffer Relocation Bracket

This model involves relocating your AMS buffer to the back of your AMS with a bracket. This reduces filament change times by as much as up to 44%. This time savings will vary depend on print time and number of color changes etc. It also creates less strain on the motors, but most importantly saves you time. My default profile for the P1S my filament time changes are about 30 seconds. With my new custom profile my filament time changes for load is around 4-5 seconds, and unload 6-8 seconds. This might not seem like much until you are doing many color change prints. Here is an example I did, I made a print that was 55:22 and 19 color changes, after this mod the same print was 44:57, that's a 11:25 min an 25 sec faster, or 18.81% overall reduced print time. 

I added a picture looking from the top of the AMS, the pictures from the back are a little deceiving. Some have said that it has 90 degree bend coming out of the AMS. The bend is not 90 degrees, it is a upwards and outwards to the buffer to make as gentle of bend as possible.

This model was inspired by several other models, most of which were only for the AMS version 1. The idea for this model primarily came from Isaiah from this model The Buffer Holder. Sadly it was only for AMS version 1. I also really like the AMS Speeder from 4Designs, but it's a 5+ hour print. So I decided to make my own version that will fit the AMS 2Pro and prints in under 2 hours, I also made this bracket thicker to better align with the PTFE tube coming out of the AMS. If you have the option there is a optional TPU insert. I highly recommend the TPU insert. There is holes on the bottom edge where you can tie up any cables etc.

Please Note: This buffer mount will not work with the new P2S buffer.

Printing tips:

1. Please use the .3mf files as there are critical areas strengthened around the thinner parts of this model. Also pay attention to model bed orientation, as it need to be printed vertically. 
2. I recommend using PETG, but  PLA should work too. 
3. I'm using calibrated Sunlu HS PETG, 255 Nozzle and bed 70.

Assembly:

1. Run the screws for the buffer in to make the threads easy before installing the buffer.
2. The supports come off pretty easy with a little care. You might have to clean up the edges of the TPU recess from the supports. This will make sure the TPU pad fits in the space properly.
3. Make sure to give a nice smooth bend to the PTFE tube coming out of the buffer to the printer.
4. I would also highly recommend 4Designs Buffer tube guide and cover. 
5. I'm using the lightweight AMS riser. This raises the height of the buffer mount where the 4 pin cable will not reach. Your installation might vary. I extended mine myself, but I have heard that the A1 AMS lite extension cable will work. 
6. You can adjust your load time and unload times accordingly in the printer settings. It really depends on your tubing lengths. I think around 13-16 is a good place to start. Mine loads in 4-5 seconds and unloads in about 7-8 seconds.
