Finished an Anet A8 cabinet with plexiglass and Mainstay Parsons table and wanted to keep stuff as simple as possible. So in order to avoid drilling the plexiglass for hinges and a handle I opted to one panel to be completely removable and hold in place with magnets. This design came from necessity as the panel was kinda hard to remove. The function is pretty simple, place on plexiglass anywhere you want using the long groove a little drop of super glue will hold it in place and use the ring as a pull to open the panel, on in my case pull the panel off. Set for 3 mm plexi but could be easily adjusted.
