We've had a 3D printer (Makerbot 5th gen) at work for a few months now and I've finally gotten around to printing something useful!
I wanted to use my SV finderscope with the Tak bracket on my RC8 so I've printed up a little adapter which I can bolt the finder to that slips into the slot on the RC8. I just threaded some 6mm bolts through and it attaches really solidly.
It's a solid (100% infill) PLA print and it used probably a bit less than $2 worth of filament.
