Oversize Lee Primer Tray

Oversize Lee Safety Prime Tray PRIMERS ARE DANGEROUS. BUILD AND USE THIS TRAY AT YOUR OWN RISK. COUNT THEM BEFORE YOU START. IF/WHEN YOU SPILL THEM, FIND EVERY ONE OF THEM. The OEM tray is here: https://leeprecision.com/folding-primer-tray-2-pack.html I designed this tray because I acquired some Federal Match Grade primers. They are packaged in a box that is much bigger than the standard Lee Safety Prime tray. This oversize tray makes it possible to open the Federal Match Grade primer box, place this tray over over the top, then invert the pair to drop the primers into this tray. The OEM tray is too small to work that way. I printed with a 0.4mm nozzle and 0.2mm layer height. Do NOT slice with supports. The Base part 3D model includes 3 support rails under the tongue. (The tongue is what fits into the Lee primer feeder.) Break those rails off after printing. Clear filament gives slightly better visibility through the lid. The 3D model is included and is done with FreeCAD 0.19. Do not expect to be able to tweak a sketch early in the sequence without also having to redo most or even all of the following features. It is because this model, and PrimerFeederBase especially, makes extensive use of FreeCAD's "edge linked to external geometry" feature. Such links are very to changes in the external geometry.
