Analogue Duo owners... If you purchased an Duo Extender from Geoffrey at GuineaPigGames, you know how awesome of a product it is! It allows aftermarket flash devices to work without modification, resolves the "thick" sticker problem with some games, saves wear and tear on the system, and I also think it's cool to see the Hucard label when playing a game.

The one concern I did have after receiving my extender is how far the extender and Hucard stick out from the system. There is a lot of leverage that can be created there, and nothing under to prevent the game/extender being pushed down. I have 2 young kids and I was very worried about potential damage if something hit the extender... So I designed this support to protect the Duo, extender, and the Hucards from damage.

I used PLA Plus with Normal Zig Zag supports which are minimal. The tolerances are pretty tight, so be gentle when sliding the extender into the back of the support. I also cannot guaranteed compatibility will every release of the extender, but I will try to confirm with Geoffrey from Guinea Pig Games.

V5 - Tightened tolerances a tiny bit and added a few rounded edges to help the clips attach/detach more easily.
