Consider following me on Instagram (@SMACKMAX_). I try to post all of my projects to build a portfolio of my projects. https://www.instagram.com/smackmax_/
Breaking my white background consistency here, Pen (Cil) Case - no support, multi colour print in parts -
8 pcs M3x10 mm (hex) 2 pcs Magnet D5x10 mm
*Follow order (important): Install(4x M3) Bumpers (grey) to the pen tray - Install Lid and Case and check if everything lines up (check underside) - Insert Grill into bumper and (2 x M3), This takes some force (extra tolerance file avaible) - Install Lid (2 x M3) and Magnets 4 x (D5 x 2 mm) - Insert Pens
*Overall the tolerances are tight, as they should be :-)
*If magnet dont go in, you can use a flat surface like table - Overall should work without magnets
*Print orientation - See Picture
