I have just assembled my cheap alternative of the riser available commercially. At the local hardware store (“Hornbach”) I had me cut four 3mm acrylic panels (about 8€) and a 3mm cover board (about 2€) to proper sizes, printed the prisma shaped edge connectors and assembled the parts with screws.
Currently is the printer busy printing four corner protectors which will cover the corners. The position of the filament run-out switch is just for time being, as at will change when an fitting JST extension has been put together or purchased - I’ll probably mount it vertically right above where filament passes through the top board. Filament can then conveniently be routed from dry box top in a single and relatively short U shaped piece of tube to the sensor.
No rocket science, but I thought I’ll share that anyway simply because of the good price efficiency of this solution, compared to the available ones (or the effort, material and time to print that huge frame which can go on top).
At the same occasion had I also cut the side panels from the same 3mm acrylic board. Those aren’t properly installed yet, only the panel on the left has been put there, attached with sticky tape. The protecting plastic film is still glued to the panel. I’m not sure yet what I’ll do with the front panel - possibly hinges and two magnets to keep the door shut.
Measurements for riser panels are:
524x135x3 mm (two side panels)
520x135x3 mm (front and rear panels)
520x530x3 mm (cover)
It may appear a tad high with 13.5 cm, but is the right size for attaching one of those relatively cheap (25€) 7 inch HDMI touchscreens to it.
