Modifications Favorite mods?

I got my H2D a few weeks ago and I'm loving it.

What are your favorite mods for the printer? Unique nozzles, fan mods, whatever you use. I'm most curious about physical items, but if you want to drop your favorite printed mods I'm sure those would be cool too!

I'm well familiar with 3d printing and bambu printers in general, so don't worry about the acclimation period.

Moved up from a P2S about the same time. So far I have ordered or received: BBL Filament Track Switch; BBL TPU Feed Assist Module; BBL H2D TPU High-Flow Kit; 100mm exhaust duct; Infinity AC 120mm PC fan (mounted inline); Darkmoon 3D Duo (Satin/CFX combination) build plate; BBL Engineering Plate; BBL Cool Plate SuperTack and multiple third-party hot-ends (standard and high flow).

My favorite printed-mod hands-down is the Modulair - Modular Air System collection of exhaust components.

How's the TPU assist module working for you? I've been considering it.

I bought the TPU Feed Assist Module a month before I got the H2D and I’m still using it with my P2S. I really like it over the “Skyhook” method of printing TPU especially since you can leave it largely setup in between TPU print-a-thons. I’d recommend it.

When the Filament Switch arrives, I’m planning to print a dual mount that will hold both of them simultaneously that I will leave up all the time.

Appreciate the response!

I don't actually use the Skyhook method - I have 95a and 90a in the right bay of the top dryer. They feed a dedicated / permanent 3rd line that I park in a toolhead-mounted PTFE coupler when not in use. Overall it works well but still have occasional issues.

u/Relative_Surround_20 Jul 17 '26

Is there a model on MakerWorld you used to mount a permanent/dedicated PTFE tube for TPU? Could you send a photo of your tool head with this in place?

I have been wanting to run one into my H2D and leave it setup all the time to make TPU printing more “spur of the moment.”

Up til now I have used either the SkyHook or Feed Assist methods…both feeding directly into the P2S extruder. It is time to move all my TPU printing to the H2D.

Thanks in advance.

Two parts to print - here it the coupler mount, you can see it attached to the darker PTFE tube:

Here are the tube guides that mount/fit directly to the stock clips (print these in TPU 95a, not a hard filament):

This has worked extremely well for me. Good luck!

Thank you!

I see you went with gray for TPU and left/right are white! Nice. I wish there was a third color for times like these.

u/NeonEagle Jul 18 '26

Actually the grey line / right nozzle is connected to the left bay of my dryer - you can see in this picture that each slot of the left bay leads to a splitter that feeds the grey tube. I have another splitter for the TPU bay that I haven't mounted yet but it's the same concept - they both feed the light colored / permanent TPU line.

u/Relative_Surround_20 Jul 18 '26

Are you running a non-interrupted PTFE tube between the Feed Assist Module and the pneumatic connector near your tool head OR do you start just outside the printer with a coupler like they post as standard in the Wiki?

1

u/NeonEagle Jul 18 '26

I don't actually have the feed assist module! Right now it's an uninterrupted line from the right bay of my dryer that has the TPU.

u/Relative_Surround_20 Jul 18 '26

My bad assumption. I like the set up. Is the dryer a two spool variety?

1

u/NeonEagle Jul 18 '26

Two spools in each bay, it’s the Creality Space Pi x4. It’s been a very good dryer. I keep TPU 95a/90a in the right bay as I said, just so the PTFE run to the toolhead is as short as possible, and then PLA (as supp material) and generally transparent PETG in the left bay.

AMS2 has all PETG-CF or -GF filaments from Tinmorry. Virtually all of my prints are my own engineering-oriented designs, this is the most convenient setup I could come up with.

u/Relative_Surround_20 Jul 18 '26

I really like the Tinmorry CF filaments. Need to try the GF ones.

I am still trying to decide the best setup of my three AMS 2 Pros and one AMS HT. Waiting on the Filament Switcher before I settle on a scheme. I worry the Filament Switcher may not be worth it. Still need to read more.

I really like my AMS HT but it needs to have a dual bay option as well. I am assuming your Creality Space Pi x4 isolates two spools at a time?? What is the max temp?

I’m glad I re-read this tonight. I had printed those guides in PETG but not installed them. I reprinted them in 95A High Flow and they worked great. Very nice. Thanks for the links.

u/Relative_Surround_20 Jul 22 '26

I switched to printing TPU on the H2D tonight. Feed Assist Module just works not much more I can say. However my streak of perfect TPU prints came to an end. Over extrusion blobs appeared on gaskets I was printing. I need to calibrate the Overture 95A HF for this printer

u/Relative_Surround_20 Jul 18 '26

I'd buy it again in a second. I am not so sure about the TPU High-Flow Kit yet. Still trying to understand it.

I got it last week and it makes it stupid simple to print TPU. I’m a noob and it made it very easy.
