I remixed this from Vaustick's Joycon Holder for Ikea Skadis Pegboard to work with Sy's Peglock system by StellasFun. I used the Negative Boolean Body for Sy's Peglock from RileyEnginerd found here : https://www.printables.com/en/model/845580-negative-boolean-body-for-sys-peglock/.

Thanks to all the great creators who made this a breeze. You all rock!

The editing was done in Windows 3D Builder.
