**MMC Mini Mounting Kit**
This is a [mounting solution](https://forum.makersmakingchange.com/t/cost-effective-assistive-technology-mounting-solutions/192?u=mmc_jake) under development for mounting the LipSync and other assistive technologies.The mounting kit is designed so that the components can be combined in different ways to create a mounting solution for a specific user and situation. A picture of the current mounting kit can be seen here:
The current kit is comprised of 5 main components:
* Links (250 mm)
* Pivot Joint
* Elbow Joint
* Tripod Clamp
* T-Slot Clamps
The majority of components are 3D printed using ABS filament and use 1/4″-20 UNC hardware. The Links are made of 1/2 inch (12.7 mm) diameter aluminum rod that is commonly available in hardware stores. They are cut to length, capped with 3D printed End Caps, and covered in 3/4 inch diameter heat shrink tubing. A hex key is used to tighten the Elbow Joint and Tripod Clamp. Extra End Caps are provided for making additional Links.
Here are a two example configurations:
1. Wheelchair side mount for a switch:
This is a standard configuration for connecting to a power wheel chair with a slotted rail (e.g. Invacare). The 3D printed T-Slot nuts can also removed to be used with through-hole connections. A switch can be connected to the Tripod Clamp with a suitable camera mount adapter.
2.Table mount for a [LipSync](https://makersmakingchange.com/project/lipsync/),an alternative pointing device:
This configuration uses a few additional components to mount a LipSync for use at a desk. The T-Slot nuts are removed from the T-Slot clamps and are used with two 3D printed [C-Clamp Adapters](https://makersmakingchange.com/project/c-clamp-threaded-adapter/). Two c-clamps are used to affix the mounting solution to a desk or table. A LipSync can be attached directly to the tripod clamp, or using a Mini Ball Head (shown here, e.g. https://www.amazon.ca/Degree-Swivel-Camera-Tripod-Ballhead/dp/B00N3NR27U) or Magic Arm for more adjustability.
* ABS can be difficult for some people to print due to fumes and safety concerns. PETG may be a good alternative, but testing and design refinement is required.
* Many of the 3D printed components use brass heat set threaded inserts. These take up minimal space and provide a strong connections for threaded fasteners, but can be difficult to install correctly and are hard to source in small quantities.
* Some power chair rails have slots that are too narrow for the current T-slot nut
* Some of the 3D printed parts can crack if over-tightened
This is a partial list of additional components that would be helpful:
* Quick-release / easily adjustable tripod mount
* Adapter for round tubing
* Clamp for headrest post
* Locking swing-arm (so AT can be swung out of the way and then returned to the same position)
* Adapter for dual-rail power chairs
This project is not listed on the website yet, but several kits have been sent out for testing purposes. If you’d like to create the components yourself, the files are available here:
This kit is still a prototype, so it should not be used for safety critical applications.
If you are keen to get directly involved in the 3D modeling, I can add you to the Fusion 360 project if you send me a DM with your email (associated with your Fusion account).
Feel free to post images of your own configurations/designs and any recommendations for changes you would like to see in the existing design or additional pieces that you feel are missing from the kit.October 28, 2019 at 8:36 pm #9406
We adjusted the above design to meet the specific needs of a student at school. For set up, they wanted the design to be something usable, but also allows other students to come to the desk to work. We found two pivot joints instead of an elbow clamp for an easier adjustment to match the clients needs.
