I'm just starting to think about a very simple tool head (yes, I haven't even built my machine yet but when I can't be building I want to be designing). There are a few things I have been wondering. - Is printing the receiver feasible? I purchased an extra tool plate to work on an extra tool but it does not come with a receiver, so I'll need to make one somehow. Obviously tolerances won't be as good on a printed receiver but hopefully it would still be possible. Some metal would need to be inserted for the magnetic pickup but that should be straight forward. - I haven't been able to find details of the clearance required for the shaft coming through the tool plate in the source files yet. I assume there should basically be a keep out zone around the ramp but I'm just trying to work out the needed extents. - Are there specs for the countersunk screws that go into the backside of the plate? I can obviously work this out from the STEP file but if someone knows offhand what they are that would be great. Would it be the case that this picture from the guide would represent the absolute minimal tool (assuming that both screws are inserted instead of just the one) that could be successfully docked and picked up. I see a few people have started looking at tools already so maybe someone here as already thought of these things.
