Work Tray for Small Projects with Gridfinity: For Smaller Printers

I saw this model and thought it was an amazing idea. However I have two Prusa printers with smaller build volumes. So this this is an attempt to optimize the model for printing on smaller printers. It would also add for some more modularity if someone needed more/less Gridfinity bases or something else entirely.The modifications from the original model include:Slicing of the tray into 4 sections. They are held together with the same 6x2mm magnets as the Gridfinity system. There is a peg included if you'd prefer to glue the sections together.Removing material from the Gridfinity bases while adding 6x2mm magnet holes on the bottom of the tray.Increasing the mat thickness by 1 mm to accommodate the magnets and raising the tray around it to match.
