Ken Hackbarth, Christine Baudin, and Michael Dicpinigaitis: Using 3D Printers to Make Inexpensive AAC Keyguards

This week, Chris interviews Ken Hackbarth, Christine Baudin, and Micheal Dicpinigaitis about 3D printing custom items related to assistive technology, including keyguards! Ken, Christine, and Michael share about discuss Ken’s website volksswitch.org, which has resources for how to create files for 3D printers that tell it to build a keyguard that fits an iPad with AAC apps perfectly.

Before the interview, Rachel and Chris talk about environmental core boards (e.g. “playground boards”) and some considerations to make before you install one, including making sure that the board is at the correct height for the students who will be using it.

Key ideas this week:

🔑 Keyguards are applicable in many instances where you wouldn’t initially recommend them. They can help individuals with moderate motor control take advantage of larger language sets by helping them effectively select smaller buttons on an AAC device. Volksswitch provides free, ready-to-print keyguard designs for a collection of popular AAC apps and popular iPad cases!

🔑 One great thing about volksswitch.org is that they provide an app that lets you customize your keyguard based on several common combinations of iPads, cases, and the most common AAC apps (e.g. LAMP WFL, Proloquo2go, TouchChat). This allows someone with limited coding and engineering experience to create and print a keyguard effectively.

🔑 Michael sells 3D printed keyguards on his Etsy website, https://www.etsy.com/shop/AdaptedCreations. In addition to selling keyguards, he also sells cases that match the keyguards, switch adapted toys, and switch mounts.

🔑 One reason that keyguards were an obvious choice for 3D printing is the high cost of getting a keyguard professionally laser cut (approximately $80-$150). As as long as you have access to a 3D printer, you can make many keyguards for the price of one laser-cut keyguard.
