Hinged lid with gas spring for Original Prusa Enclosure

Overview:

I am pleased to introduce the revised upgrade for the Prusa Enclosure - making it possible to open the lid of the enclosure automatically using gas springs. With a simple push of a button, the lid can be opened easily and allows direct access to the inside of the Prusa Enclosure.

After the alpha release, I completely revised the Prusa Enclosure Upgrade. The handle has been changed to a simple push button, which makes the closing function even better.

The lid, which bent quite a bit in the Alpha version, has been reinforced with aluminium profiles. This has reduced the bending to a minimum.

Assembly of the frame:

Firstly, the hinges must be mounted as described here .

After that you can start assambling the frame.

To do this, first insert the M3 nuts into the slot nut - cross brace and then slide them into the shorter aluminium profile. The slot nuts should first be loosely screwed to the brackets. They can then be pushed into the aluminium brackets.

When the frame is mounted, 3 mm holes can be drilled through the aluminium profiles.

I glued the frame to the lid with double-sided adhesive tape. To do this, the frame must first be unscrewed again. Then the adhesive tape can be applied to the frame and then the lid can be screwed back onto the cover. You can get the exact position by using long screws and then using them for positioning like you can see here:

Mounting the handle:

First insert the square nut in the handle.

The spring can then be inserted into the handle together with the handle pusher. The spring does not have to have the exact dimensions specified, only the diameter must not be larger than 10 mm.
