Update November 16, 2023

Version 1.1 of the Hydra AMS - Silica Dry Boxes is released. 

Changes:

• Increased size / capacity, rooms around 37% more silica gel beads.
• Height slightly decreased for easier fitting.
• Reinforced handle, shorter and stronger.
• New and enlarged font for the text / serial number versions.
• Updated all serial number boxes.

The boxes are also compatible with the stock AMS, Hydra AMS is not required.

Update May 7, 2023

Added a version for rectangular hygrometers. It fits this style of Hygrometers:

• Mini Digital LCD Thermometer Hygrometer (Rectangular)

This version needs some supports where the hygrometer is placed since it's as wide as the box itself but it prints very easily as well. Shown here without silica or lid installed:

About

This is a set of front mounted Silica Gel Boxes for the Hydra AMS, both to lock the front of the Hydra in place and to keep the AMS dry. 

The stock Bambu AMS has tabs in the front to lock it in place while Hydra does not as the print height of the Bambu printers is not tall enough to allow for that so these boxes ensure the Hydra printed parts gets fully pressed down in the front as well. They're however optional and Hydra function fine without them.

There are a few different ones:

• Clean - No print
• “Hydra”
• “AMS”
• “PRO”
• With Hygrometer
• With Serial #

Tip: Check fitment with one box first. If it's too tight to fit you can scale all parts to 99% and print it again. Tight fitment is intended but if it's too tight you can try this.

BOM - Bill of materials

Silica gel beads. There are a couple of difference options, if you're in the US I recommend going with the ones from VOXELPLA (top link) who is a partner.

• Replacement Cobalt-Free Silica Gel Drying Beads (1lbs)
• 500 g Silica Gel Beads

I bought my beads before I was aware of the colour changing ones so mine are just clear. For the Hygrometer box you also need a small round hygrometer (mini) with a 41 mm diameter which you can pick up from AliExpress for example. I bought a bunch since they're so cheap:

• Mini Digital LCD Thermometer Hygrometer (Round)
• Mini Digital LCD Thermometer Hygrometer (Rectangular)

You also need an M3 hex bolt (socket head), anything from 6-10 mm should work. If you don't have any at home it's best to grab the kit below, it will have everything you need for this build and many more.

• 1100 pcs M3 Hex Socket Head Cap Kit

Optional

I highly recommend these Nano Coated Helical Extruder Gears from FYSETC, I use them for all my Bambu printers, they're inexpensive and offer a number of improvements of the stock gears:

• Extruder Gear for Bambu X1/P1P/P1S CNC Nano Coating

The hex tools are optional and you can of course use any hex tool but I like these and have used them for years for my printers:

• Hex Tools

How to use and install

Fill the container with silica gel and slide over the lid. Secure the lid with a M3 socket head, the hole is threaded, you don't need to tighten it very much.

Next, install it between each feeder. Press it all the way forward against the clear/smokey plastic at the front of the AMS to lock Hydra in place.

Here is my second Hydra AMS with the boxes in pink and the middle one with the optional Hygrometer.

View from above. The lids have a handle so they can easily be installed and removed. It's easiest to do with the spools removed, although you can do it with spools in place.

Silical Gel Boxes based for Hydra AMS, stock AMS is also compatible.
