This is an accessory for the Elegoo Neptune 4 Plus printer. Maybe suitable for other similar Elegoo printers too.

If you have ever experienced warping of your workpiece during printing, but the adhesive was so strong that the workpiece did not separate from the PEI build plate, it may be that the magnetic surface of the heated bed did not hold the PEI sheet firmly enough, causing it to bend and separate from the heated bed. This is prevented by this small clip, which secures the PEI build plate at the edges.

This mainly occurs with filaments that warp significantly during printing, such as PA.

Recommended printing settings:
Material: PA12
Printing speed: 20mm/s
Printing temperature: 15°C below the maximum temperature recommended by the manufacturer
Wall loops: 8
The filament should be thoroughly dried (8 hours @ 70°C), use a closed printer housing.  Use a brim width of at least 10 mm with a brim gap of 0 mm. At the end of printing, carefully cut off the brim with a knife. Use a suitable PA adhesive (e.g., Magigoo PA or Vision Miner Nano Polymer). First print one piece as a test to see if it fits tightly enough on the PEI sheet and heated bed. It is good if it is not easy to snap into place. If it snaps into place easily or is too tight, reduce/increase the model size proportionally by a few percent in the slicer.

I modified the design slightly so that it would not collide with the print head.
