If you like reel-to-reel compact cassette look and you don’t want to spend a fortune then you can create one – using 3D printed reels.
Just download attached zip file containing STL model files. Print it with the highest precision (0.1mm layer height, 0.3mm nozzle diameter, 100% infill). I use PLA filament.
Then follow assembly video bellow.
Model files: Cassette_reel_STL_v9A.zip
Note: It can be better to glue base part and top part together. Otherwise it might loose during the time and cause friction between reel and cassette body.
Note: you can use these model files for your own non-commercial usage!
If you want to have text or logos on the reels then you can use “rub on decal” transfer sheets (available at eBay) for inkjet or laser printer.
