If printed at original size, the holes are made to fit #6 standard bolt and hexnut hardware. Have not tested it, but M4 parts should also fit. So far it seems to be very strong when printed with 100% fill.
We had a problem using our MakerBot Mini spools on our Bee the first so we designed a very simple adapter that snaps on the original one to fix the spool into place. It works surprisingly well. It's a quick and effective hack to use all the MakerBot PLA filaments.
A 3D printable stand for your 3D printer filament spool. A free-standing design and wide enough for most aftermarket filament spools like those sold at 3DPrinterNinja.com. You can download the CAD models from my site if you like.
