This is a case designed to close with a single key, ill send instructions but you can modify it if needed to fit your precission tolerance of the printer. Ive designed this to print in a resin/UV based printer such as Elego Mars. I have enjoyed a printout recently, but due to limited resources, i couldnt reform it yet and if you please can update it further, do send me ideas! the cbddlp file is for direct print to Elego Mars printers *maybe some others too.
