Based on the very good model of ER605 & OC200 Rack Adapters (V2) by Sorcier, I remodelled them to fit 2x TL-SG2210P. It's a heavy device, and 2 of them in this pair of brackets are recommended to be supported, either by support angles or a more solid rackmount device below them. This is my first attempt at 3D Modelling, and I only made this to fulfill my need of Rack Adapters for my devices, so I apologize if this model isn't suitable for everyone.
The author remixed this model.
I modified the cage of ER605 to fit TL-SG2210P (209x126x26mm), thickened the cage base by 1mm, and shrunk the middle joints to accommodate the device width.
