IKEA Skadis Mountable SSD Heatsink Base for NVIDIA Jetson Orin Nano Developer's Kit Case

IKEA Skadis Mountable SSD Heatsink Base for NVIDIA Jetson Orin Nano Developer's Kit Case

Modified base for Harrison's NVIDIA Jetson Orin Nano Developer's Kit Case (linked below). Can be combined with any main case part from the original model or its remixes.

Features

Like in the original model, the Jetson Orin Nano Developer's Kit sits on top of the base, and the base protects the underside of the board.

Key features of this model:

1) Space for an SSD heatsink

The Jetson Orin Nano board has M.2 slots on the underside of the board for SSDs. The developer's kit comes in a plastic frame that offsets the board from the floor, but it's not enough of an offset to fit a heatsink.
This base has enough space to fit heatsinks similar in height to the Crucial P310 heatsink.

2) Vents for airflow to the underside of the board

Vents on two sides and on the bottom. No fans, just holes.

3) Mountable to IKEA SKÅDIS pegboard

Optional feature.
The Jetson Orin Nano Developer's Kit can be mounted to a Skadis pegboard in two orientations: I/O panel facing left or I/O panel facing right.

4) Slots for dust filters

Optional feature. The print gets a bit more complicated if you choose to include these.
I used 0.45mm thick PVC mesh as the dust filter. Product link: https://www.amazon.com/dp/B09Y336F2R

Measurements

Exterior dimensions

Exterior dimensions (excluding Skadis hooks) are 114mm x 103mm x 14mm.

Interior dimensions

Interior dimensions are 98mm x 87mm x 7.80mm. Maximum depth goes up to 8.50mm in the center.

The base should be able to fit a heatsink that sticks out up to 7.50mm from the bottom of the kit, leaving at least 1mm of space between the heatsink and the case to prevent warping (use your best judgment based on your filament & SSD temps).

I installed a Crucial P310 SSD with Heatsink on my board, and it fits in the case with ample clearance:

Side dust filters

The side air vents have an optional slot for inserting a dust filter.

The slots are 0.50mm thick, 9.80mm tall, and 87.00mm wide. I cut a 0.45mm thick PVC mesh to size (slightly smaller than the slots) and fit it into the slots. https://www.amazon.com/dp/B09Y336F2R

Bottom dust filter

The bottom air vent also an optional slot to insert a dust filter from the exterior side.

The filter needs to be kind of squeezed/shimmied into this one. The dimensions of the exterior hole are 98.00mm x 51.10mm, and the dimensions of the space inside the slot are 102.00mm x 55.10mm. I cut my PVC sheet to ~ 100mm x 53mm, and trimmed the corners off to fit it into the slots more easily.

The thickness of this slot is 0.70mm. A bit of extra clearance to account for bridge sagging in the print.

About the model files

Versions/variants

There are two versions of the model, in separate folders. Choose Skadis version for a base that mounts onto IKEA Skadis, and Non-Skadis version for a simpler base without the Skadis parts.

Both folders have multiple variants of the base:

1. no_filters: no dust filter slots

2. side_filters_only: has dust filter slots for the side vents only

3. all_filters: has dust filter slots for all vents (sides and back)

4. all_filters_custom_supports: has dust filter slots for all vents and custom print supports

The no_filters and side_filters_only variants should be easy to print with basic settings & supports.

The all_filters variant is a bit tricker because of the dust filter slot for the bottom vent. I used custom supports to print mine, which are included in the all_filters_custom_supports variant (see "About the custom supports variant" for more info).

For the Skadis version, you need to print the hook parts as well. These are an adaptation of the screwless version of LayerCake's IKEA Skadis Xbox One Controller Holder With Lip. Insert the hook parts into the back of the base first, then snap the lock parts into place.

Test print files

The test print folders contain test print models for each of the base variants for testing out print settings on all the features with less filament.

My print settings

Because I printed fully in PETG, I also inserted pauses into my print to add PVA glue (glue stick) between the supports and the print for clean removal.

My PETG tends to ooze during pauses, so I prefer to actually do a filament change (reinserting the same filament) instead of a real pause.

About the custom supports variant

The custom supports variant of the model includes:

Support enforcers & paint-on supports

This variant of the model should be printed in its current orientation, with support settings set to "For support enforcers only" (or its equivalent in your slicer).

Bridge modifiers

Modifiers to fine tune print settings for the bridges that don't have supports.

I modified the Bridge flow ratio and Bridges speed to values that work best for my PETG filament. Replace the settings in these modifiers with what works for your filament and print settings.

You can also delete these modifiers and paint on supports to these areas instead.

Custom supports added to the model

Small support bars in the gaps for the bottom dust filter slots. These need to be cut out with a knife after printing.
