Sorry if this is a repost and is already on another thread.
I've been trying to find some clear plastic box protectors to my consoles & peripherals like the ones running on Ebay for Gameboy/SNES etc but none of the sellers are currently making those boxes as they are quite big. There are protection boxes for some Mega Drive models but never seen for Master System so far.
I just started to make my own protection boxes with the same plastic thickness and the results were quite good actually. It looks great on the shelves and it's nice to keep them protected. It's not as perfect as being made and cut by manufacturers but it does the job quite well.
So far I have done for my Master System Plus and my Master System II. Will start now to the Master System II Plus and then keep working on my other consoles, light phasers, control stick, 3d glasses, etc.
That's great, a glass cabinet is nice for protection and display, you won't need anything else. I live in a house free from smoke and pets but it's always good to have them protected.
As for the boxes, I just took the measures from my consoles as accurate as possible and trimmed them so that the consoles could fit nicely and shape. The peripherals will be easier to make as boxes are quite smaller comparing to consoles (specially Master System Plus lol).
Fred Aldous and Paperchase sell this type of plastic sheets, it's possible to order online as well. I just paid around £3 per sheet so it's quite cheaper than paying the £25 on ebay and it does the job.
