M3 Rosettes for Spring-loaded Platform Adjustment

Rosettes for M3 nuts that make spring-loaded leveling easier. A lot easier. I even reach in and give them a quick tweak while the first layer is printing.


I made these a few months ago and forgot to post them. Aside from the rosettes, my leveling method is darn close to haqnmaq's recent Thing: http://www.thingiverse.com/thing:6558

The rosettes are useful anywhere, of course, but I made them specifically for leveling the build platform on my cupcake.


The gist:

• Three screws instead of four (with four screws one nut always seems to end up loose)

• Conical springs (I kept bottoming out on one side. Conical springs can collapse almost flat) and M3 thin nuts to keep the platform from getting too tall.

• Flathead screws to avoid collisions with the extruder nozzle.


I ordered my conical springs from McMaster. They're very nice, just the right size, and strong....but $14.73!? For three springs?!?! Later I realized that I was surrounded by conical compression s
