Download the Fusion 360 file and enter your custom dimensions (Modify, Change Parameters in the Design Workspace).
I just recently got myself one of these neat electronically height-adjustable desks. With this purchase came the necessity to mount several power supply units onto the moving plate. I'm planning to get some serious cable management going, but that will take some time and I want to use the desk without too much dangling cables.
It took something like 10 minutes of design-time and 25 minutes of print-time for each bracket. I did several sizes for the different power supply bricks and an USB Hub. I love it.
Key Features
Parametric Source File
Find the attached Fusion 360 file with neatly organized user parameters to customize e.g. height and width. Be aware that the geometric constraints used in this model are a challenge for Fusion to solve. The base sketches tend to get stuck when changing width. When you get an error, close the Parameters dialog, undo and try again in smaller increments.
Designed for printing
This section is only relevant when using a slicer engine other that Arachne! The Fusion 360 File contains parameters called nozzleWidth and targetThickness. The actual thickness of the bracket is meant to be printable with an even perimeter count to optimize print time and quality. Adjust these parameters as needed.
For the material I would suggest using PETG. Especially when mounting power supply units that tend to get hot when used, PETG is better suited than PLA.
All perimeters, no infill
Set infill to 0% and increase Perimeter Count as much as necessary to get a solid object. This will lead to extrusions that follow the curve of the object.
Pre-tension
When designing a bracket you will need some preload on the brackets arms to force the holding hooks around the object. I designed these brackets to get this preload from a curve at the bottom of the model. This has the advantage, that when mounted, the corners of the bracket stay in contact with the surface it is fixed to, which makes it more rigid as opposed to a bracket with angled arms.
Vertical mounting options
My use case is restricted to mounting blocks to hanging brackets, but as an afterthought I added a component to the Fusion file that has endstops to allow for vertical mounting on walls or similar.
