Added a "v2" STL version which moves the USB port more centered to the floppy drive opening, widened the original 3 digit LED display cutout and moved it back slightly to now support an OLED display for use with firmwares such as FlashFloppy, please see the documentation of FlashFloppy for more details but the OLED type is a common inexpensive one found on ebay "0.91" IIC I2C Serial SPI OLED LCD Display 128x32 3.3V/5V AVR PIC STM32 Arduino"
(Sep 3, 2017) This is a remix of the fantastic Amiga 500 Gotek USB disk drive emulator base but for the Amiga 3000 desktop computer. Please see the original by CrazyBob for additional details.
To mount this in an Amiga 3000 you will need the metal drive sled in that comes with the Amiga 3000. I simply screwed this gotek sled to the drive plate from underneath (where the little metal tabs are) up thru the plate's screw holes into the plastic sled. (the same if you were placing a hard drive into the metal sled).
(the last photo shows the --unpublished at this time-- LCD floppy bay cover, that works like the original floppy bay cover (clicks into the drive slot) and is removable allowing you to use your original floppy drive if desired (configured as DF1 with the Gotek as DF0).
For aesthetics I recommend using a mini OLED display which will fit in the original gotek LED display cutout, therefor not requiring the external LCD clip-on drive cover holder. http://www.ebay.co.uk/itm/302110929185
I also HIGHLY recommend flashing your Gotek with Keir Fraser's excellent "FlashFloppy" gotek firmware (much better than the old Cortex and works like HxC but free to use), it supports LCD displays and floppy sounds!
I used 0.3 (you can use any)
50% for strength (your choice)
As the drive eject button is rather small, I suggest using supports to have it print out nicely.
