This is a direct replacement for the commercially made ones and serves the exact same purpose: covering a hole in your wall material. Sometimes, you need to cut into your wall and keep the opening, and other times, I am just too lazy to fill the hole permanently. Either way, this snap-in panel is fantastic. It looks good and draws no attention.

Operation is simple: just press the sliding edge of the snap-in panel onto one side of an 8-inch x 8-inch hole, and compress the compliant spring far enough that you can rotate the panel and get the fixed edge of the snap-in panel into the hole. Release the spring pressure, and the panel is held into the hole by the remaining spring tension.

The compliant spring system is quite robust, but I nonetheless recommend printing the spring part with PETG. PLA worked fine in my testing,g but I do not know if it will perform as well over time.

Print Settings

Functional designs (such as this one) generally require more strength than non-functional designs and more strength than the typical default slicer settings provide, so please review your slicer settings carefully.

This product was designed for a 0.4mm nozzle, a 0.2mm layer height. For best results I suggest the following:

• Material = PLA / PETG for the panel, PETG for the spring part.
• Nozzle = 0.4mm
• Layer Height = 0.2mm
• Line Width = 0.4mm
• Wall Count = 4 (1.6mm)
• Top and Bottom Layer Count = 5
• Detect Thin Walls = ON
• Wall Generator = Arachne
• Infill = 40% (Cubic)
• Support = None required
• Print orientation = As per the STL/3MF files and the included image

Assembly Notes

After printing, the parts go together as illustrated.
