SmallRig RC to Nanlite FM Adapter

This adapter will allow you to mount your Nanlite light modifiers on SmallRig RC COB lights such as the RC60B or the RC100B. 

Features

• Sturdy design optimized for FDM printing
• Minimal mount distance offset
• Lock ring with trapezoidal threads
• No screws or inserts required
• Built-in supports

Print Requirements & Settings

• ABS/ASA for best temperature resistance
• 0.4 nozzle
• 0.2 layer height
• 0.25-0.3 first layer height
• 3-4 walls/perimeters
• 20%-40% infill
• Arachne wall generator

Slicer Prep

Prior to printing we need to make sure that the built in supports will be removable and are sliced correctly.

	First, check that the main (inner) built in support is sliced correctly by looking for two concentric lines where the support connects to the main body, each line should measure one wall thickness as seen in the reference image below. This support is intentionally left connected to the rest of the adapter body, It will be difficult to remove but this ensures maximum quality.
	Secondly, ensure that the three small built-in supports holding the overhangs are correctly sliced. The first layers of the support and the protrusion above should show as “overhangs” in the slicer.

Assembly

	Start by removing the three small supports. They should slide out easily from under the overhangs. Pliers make it easier to pull them out.
	Remove the big inner support with a pair of pliers. Grab the ring and pry out the support. This might take a while. Loosen it up on all sides or try pushing it out from the other side. It will seem like it doesn't want to come out, but it will eventually. Take a break if needed.
	You did it! The hardest part is now behind us.
	Thread the locking ring over the adapter and loosen it by threading and unthreading several times. If it still feels too tight, keep at it until it threads in nicely without resistance. As a last ditch measure you can add some PTFE lube to the threads for extra smoothness.
	Thread in the locking ring until the holes on the ring align with the holes on the adapter.
	Insert the adapter onto the bowens-style mount of your Nanlite light modifier and lock it place by rotating the lock ring fully. Note that removal may be difficult. If the lock ring is stiff, use pliers to rotate the ring anti-clockwise until the holes are aligned again.

Notes

I tested the adapter with a Nanlite FL-11 but should work with other light modifiers and accessories that fit the Nanlite Forza 60 II, 60B II, 60C, 150, 150B, FS-60B.

Because the adapter doesn't protrude too much in front of the COB, heat isn't an issue, however, for best results I would print in ABS or ASA but PETG should also be fine.
