KIT TO CREATE CHEAP SHOWCASE
I made this little kit (3d printed obviously) to build the showcases for model cars since they cost a fortune.
With 10 € of plexiglass sheets (however it depends on their size and thickness), on Amazon and some interlocking dowels you can create boxes of all sizes, which can be opened from above, can be dismantled for transport, and if desired, with attachment for the padlock. (Not printed in the photos).
Glue NOT needed.
2 or 4mm plexiglass sheets depending on your taste, if you want you can print the raised kit to insert the colored LEDs underneath.
