LCD Bracket/Spacer For 15.6 GRS Pincab LCD
Description
This thing has a fairly specific use case, and I wouldn't be surprised if I'm the only person who ever uses it. On the virtual pinball kits that you buy from gameroomsolutions you can order a 15.6" cut on the backbox for the DMD. However, their recommended solution to keep it in place is to stick some double sided tape in there, which is less than ideal. Bad tape quality, tape wearing out, movement, or any number of things could cause the tape to unstick and the LCD to fall backward inside the backbox. So I designed these little brackets or spacers or whatever you want to call them. They're meant to fit into the pre-routed notches at the top side of the 15.6" panel cut, and screw into the thicker 3/4" MDF next to the notches. Use/print/install these at your own risk of course. V2 has a tiny bit of wiggle room between the LCD and the bracket (1mm) that is meant as a small safety to keep the LCD from cracking the **very thin** piece of wood it rests against. V1 has no such gap. Different printer tolerances or metal tabs on other LCD panel brands could prove to be a different thickness, which would apply too much pressure and crack the wood. Using either V1 or V2, I'd be extra careful when screwing them into the wood and stop if the metal tab starts push against the wood. Make sure you drill pilot holes for the screws too, or even the thick 3/4" MDF will likely crack. Be careful not to accidentally drill all the way through. I printed two of the V2, and used 1/2 inch #6 wood screws, and some cotton from the end of a Q-tip to remove some slack in the 1mm gap. I still used double sided tape on the bottom tabs. I had considered just taping the 3d printed bracket to the wood, and that would likely hold better than the double sided tape since there would be a larger surface area, but that might not be as reliable as screws. I would **not** screw the LCD panel tab into the 3d printed bracket. The screw head will likely rise up higher than the 1mm gap would allow, and the thin tab of wood will crack. The metal tabs on the LCD panel should have **no** screws in them. If I were to redesign this, I'd consider making a slot in the bracket to hold the metal LCD tab instead of sandwiching the metal LCD tab against the wood. The 15.6" LCD panel I used for the pincab is https://www.amazon.com/dp/B00JMM89NC which may be an expired/invalid link by the time anyone actually reads this. If it helps, the model number I searched for on amazon was B156HAN01.2. A compatible controller for it would also be a good idea, and a power adapter for the controller if one isn't included (mine didn't include one).
