Solution for printing on glass with the Tevo Tornado.

This solution makes it incredibly easy to mount and remove the glass plate with precision. The nozzle should not come into contact with any parts due to their low height and because they are outside of the printing area or homing zone. To assemble, you will need: A glass plate with sizes shown in Thing files; An M2.5 screw that is 5-10mm long; Two pieces of 10x15x4mm bearings (6700ZZ). These bearings and washers prevent the bed level from changing when moving the front levers, making leveling smoother, so they can be used on all four legs. When printing parts, it's crucial to print them with the flat side down. The strain relief should be printed vertically, with the thin part pointing upwards. For the strain relief, you will need an extra screw. I used an M2.5 screw for my strain relief (I got it from an old alarm clock). The maximum length is 10mm, and the hole for the screw is 2.3mm in diameter. I printed with PLA. To avoid corner bolts on the Tornado from turning when adjusting the bed, I added a press fit solution. This means you will have to press (or knock) the head of the screw into the part. If the press fit solution isn't tight enough, try lowering the bed temperature during printing. Apply grease to the bolt threads. IMPORTANT: In addition to this, you need to mount Build plate bushing / stabilizer by Vektor Viktor to all four holes on the heat bed plate. They work as padding between the leveling bolt and the hole in the glass. If you don't do this, small pieces of glass might loosen in the holes. Alternatively, you can use (Diameter=4.8mm) heat shrink on the top part of the bolt threads if the holes in the glass bed are too small for build plate bushing. The heat shrink can be heated with a lighter. The part of the removable glass plate that comes into contact with the levers should be cleaned with ethanol regularly, or the locking mechanism might stop working. It's also essential to clean the round part of the levers that come into contact with the removable glass plate regularly with ethanol.
