It's printing now so if it works out well I'll post it for others to use but I made some changes to the filament guide tube spacer thing:
http://www.thingiverse.com/thing:409297 to add a switch mounting flange. It should be done in a couple hours so I'll post up when it is and add the file to thingiverse if it's successful.
On a different subject, something has come up several times recently and I'm wondering if S3D will solve the issue. I print without rafts as much as I can. It gives me better bottom surface finishes, uses less material, saves time, and generally results in better prints overall. however, plenty of my designs require support that extends up from the bed. For functional reasons on a lot of my parts I can't reorient the parts to eliminate the supports or get them to attach to the part instead of the bed. The problem is that without a raft my supports end up popping off the bed probably 50% of the time. It's even worse when one support comes up but the others don't, the whole print is shot because of a small failure. Does S3D allow the use of a raft/brim/etc. ONLY for supports and not under the part itself to improve support-bed adhesion without ruining the bottom surface finish?
