I used magnetic tape to hold the polycarbonate side panels on my printer. The advantage of using the tape is that it seals the print chamber almost air tight which helps keep heat and smell in when printing ABS. I used "matched pole" tape that comes in two rolls of opposite magnetic polarity. I found the adhesive on the tape didn't stick to my printer's aluminum frame very well, so I peeled the tape off and applied some contact cement to the frame and the clear panels and restuck the tape. No more problems.
You can see the black tape around the edge of the clear panel here:
When the panels are removed and replaced they practically jump into position on the printer frame.

Overview of the complete printer;
My goal was not to make this an airtight printer. I don't use ABS so smell isn't an issue but with my old printer I had many problems due to draft, especially during warm day's when a window was open or a fan was blowing. I hope that this will give enough protection against draft.

After a lot of messing around with the bowden setup I decided that enough was enough and that I should have listened to Felipe.
The bowden extruder is gone! And so have all the retraction and jamming issues.
This is the new direct drive setup.
The pancake drive is half the weight of a normal Nema 17, so no issues with print speed yet.
