3D Printing¶
All OWL enclosures and mounts can be 3D printed. This page provides the STL files, print settings, and guidance for both the Original OWL and Compact OWL designs.
Original OWL¶
There are seven total items that need printing for the Original OWL unit. All items with links to the STL files are listed below. There are two options for Original OWL base:
Single connector (Bulgin) panel mount
Pros: Easy/quick attach/detach from whatever you have connected, more water resistant.
Cons: More connections to make, more expensive
Cable gland
Pros: Fewer connections to make, cheaper, faster to build.
Cons: More difficult to remove, less water resistant.
We also provide a link to the 3D models on TinkerCAD, an online and free 3D modelling software package, allowing for further customisation to cater for individual user needs.
Original OWL Parts List¶

|---|---|
Original OWL |
|
OWL base, onto which all components are mounted. The unit can be fitted using the M6 bolt holes on the rear panel. |
|
OPTIONAL: OWL base with cable glands instead of single Bulgin connector. |
|
OWL cover, slides over the base and is fitted with 4 x M3 bolts/nuts. Provides basic splash protection. |
|
OWL base port cover, covers the cable port on the rear panel. |
|
Raspberry Pi mount, fixes to the Raspberry Pi for easy attachment to OWL base. |
|
Raspberry Pi Camera mount, fixes to the HQ or V2 Camera for simple attachment to the base. |
|
Relay board mount, fixes to the relay board for simple attachment to the base. |
|
Voltage regulator mount, fixes to the voltage regulator and onto the relay board for simple attachment to the base. |
Print Settings - Original OWL¶
Ideally supports should be used for the base, and were tested at 0.2mm layer heights with 25% infill on a Prusa MK3S.

Compact OWL¶
The Compact OWL has fewer parts to print than the Original OWL and is both more durable and water resistant. A complete unit requires printing of only 5 parts.
All 3D model files are available to edit and download on TinkerCAD or Printables. The 3D printing .stl files are provided under the 3D Models and through the links in the table below.
The backplate comes in three options:
Amphenol EcoMate Aquarius receptacle only
Amphenol EcoMate Aquarius receptacle + Adafruit RJ45 waterproof ethernet connector
16mm cable gland only
Pick one of these backplates when printing.
Compact OWL Parts List¶
Description |

|
Frontplate: covers the front of the enclosure. Incorporates a 37 mm lens cover to seal the enclosure. |
|
Lens mount: Securely mounts the 37 mm UV lens filter to the frontplate. |
|
Backplate: 1 x Amphenol EcoMate Aquarius Receptacle size 10 shell, 1 x size 12 shell |
|

|
Backplate: blank |
|
Backplate: 1 x 16mm Cable Gland |
|
Tray: Mounts all required hardware and fits into the enclosure body on the second rail. Use M3 heat-set threaded inserts for the lens holder. |
|
Lens holder: Secures the lens with two M3 x 6mm screws. |
|
OPTIONAL: Camera Module 3/V2 Camera mounting plate |
Print Settings - Compact OWL¶
All .stl files for the 3D printed components of this build are available in the 3D Models directory. Supports are not required but do improve print quality.

Controller Enclosures¶
3D printed enclosures are also available for the OWL controllers. See the Controller Setup Guide (coming soon in the Software section) for more details on building controllers.

General Printing Tips¶
3D Printing Recommendations
Material: PLA or PETG recommended for enclosure parts
Orientation: Print bases with the open side facing up
Supports: Required for base pieces, optional for other parts
Post-processing: Sand mounting surfaces for better fit
Threaded inserts: Use a soldering iron to set heat-set inserts
