Python - Ultimate Bambu Lab AMS 2 PRO - Enclosure Conversion Kit

About

This is a kit for converting your original Python Enclosure to a Python Enclosure for the AMS 2 PRO, it works with both the Actively Heated Enclosure and the Passively Dried Enclosure. 

The printed parts are the same and the panels are as well, apart from some more holes so you just need to drill these holes in the front and rear panels and print a few mounts for the new AMS 2 PRO front and rear vents and you'll have the Python Enclosure for the AMS 2 PRO, fully taking advantage of the new features for the AMS 2 PRO, like heaters / dryers and humidity control.

To your help I've created some drill templates for the front and rear panels.

BOM - Bill of Materials

For the conversion, you need a 4.0 mm drill bit and a 14.0 mm one and an electric drill. You probably already have a 4.0 mm one but the 14.0 mm one is a little more uncommon. 

You can buy these in most hardware stores or you can find them on AliExpress for example:

• 4.0 mm and 14.0 mm HSS drills

What to print

Print one of each of the following included models:

• drill-template-front-print-1pc-1.00.3mf

• drill-template-rear-print-1pc-1.00.3mf

• python-inlet-outlet-bracket-front-print-1pc-1.00.3mf

• python-inlet-outlet-bracket-rear-print-1pc-1.00.3mf

• python-inlet-outlet-vent-front-print-1pc-1.00.3mf

• python-inlet-outlet-vent-front-print-1pc-1.00.3mf

Print the parts in the direction I have set them, no supports are required. You can print the tools in just about any filament.

How to use

Start with the rear of the enclosure and the drill template marked “rear drill template”:

Flip it around so the text face the acrylic and press it into the lower two cutouts of the rear of the enclosure, like this:

Drill through the five smaller markings using a 4.0 mm drill bit. Do not drill the larger marking yet, this is for the larger 14.0 mm drill.

Remove the template and it should now look like this:

Install the template back and switch to the 14.0 mm drill bit and drill though fully. 

Drill slowly and with not too much pressure.

You may want to expand the 14.0 mm hole just a tiny bit by rotating the drill so the inlet/outlet mount sit fully flat but it's optional. Clean up the acrylic then mount the inlet/outlets in the next step.

Removing the inlet/outlet vents from the AMS 2 PRO Box

If you've done the Python build you've probably already done this step but if not, unplug both cables from the rear AMS power board. 

Next, unscrew the vents. The one in the rear left sits with a 1.5 mm hex screws and the one in the front right sits with 2.0 mm hex screws.

Finally remove the tape holding the cables and lift out the vents including cables. 

Installing the inlet/outlet vents and PTFE route

The AMS 2 PRO comes with inlet and outlet vents for controlling the humidity inside the box. They are mounted to the Python enclosure using a few printed parts and four M3-12 mm socket head screws.

Begin with the front mount as shown below:

The front mount and bracket does not have a hole for the PTFE tube.

Place the vent in the printed part, it can only be placed in one direction.

Place the bracket on the outside and screw it from the outside with four M3-12 mm socket heads.

For the rear vent, press in the PTFE tube coming from your printer.

If it's too tight to fit through, untighten the four bracket screws a little, this should allow you to perfectly align the holes of the panel, vent holder and bracket. Still to tight? Quickly run a 4 mm drill bit in the PTFE hole.

Nevermind the extra M14 plug next to the bracket in the picture below, this enclosure is an early beta unit. :)

It should now look something like this, the front is to the right and the rear to the left:

The cables to the vents connect to the AMS power board, in the rear of Python. This is the location, the two white plugs & connectors:

The left is for the long cable, going to the front vent. The right is for the short cable, going to the rear vent.

Guide through the cable for the rear vent next to the AMS rear motor / Filament hub and for the front vent you can just pass it through any of the lower cutouts, keep it centered so the cable reach.

Place your Python inside the enclosure. You don't have to unscrew anything of the enclosure, just carefully bend the sides and it will slide inside.

Connect the front vent cable:

And connect the rear vent. Also press in the PTFE tube into the AMS rear motor / Filament hub.

Finally, connecting the AMS bus cable, power cable for the heaters (center rear connector of Python) and any optional PTFE tubes for the external spool function. 

All done!
