This is my horizontal "widescreen" HoloBox for Smartphones, based on Pepper's ghost illusion technique. Superb for advertising stuff! Very easy build! Print out the two halves snap them together (they have snap-joints). Slide in the acrylic glass sheet or transparent laser printer foil and put your smartphone on the top on full brightness, playing your video or animation. As simple as that! I have also a “vertical” version - just check my other uploads in the profile. Think of the possibilities: Interactive, real-time animation of an Avatar combined with AI like Chat GPT, Siri, etc.
Pictures, Animations, Videos etc. that are on black background work best. On your smartphone turn "off" automatic brightness and move the slider to maximum brightness. This version is for horizontal product presentation that means your videos need to be horizontal i.e. 1920px * 1080px.
For best results you will need a special holographic reflective film. It is attached with water and dish soap to a piece of acrylic glass. With this foil you will get the best results because it also diminishes the double reflection caused by the 2mm thick acrylic glass. The foil looks like a one-way mirror foil but not too reflective. I couldn't find it on aliexpress but I ordered directly from here: http://www.defi-tech.com/holo-film-for-showcase.html
If you know of any alternatives please let me know.
You can also use only the acrylic glass but you will get a slight visible double reflection on your projection. What works good too but only in a dark environment is a piece of a DIN A4 transparent film for laser printers. These foils are only 0.1 mm thick and avoid the double reflection. In daylight the projection is pale and lacks contrast because it's missing the reflective coating. If you have any idea on different foils that might work let me know.
Size of the Acrylic glass sheet is 139mm x 85mm x 2mm

Use supports! Project file and GCODE is included.
Remove supports with pliers and use a small nail file on the snap fits and holes to make them fit. I've added 0.3mm tolerance but because of the overhangs and supports you still need to use the nail file a little bit to make it fit perfectly.
