The parts should be printed commercially for best results and strength (PLA e.g. was too weak for screws etc).
For the parts that touch the oil we printed with:
Technology: HP Multi Jet Fusion (MJF)
Material: Nylon 12, Glass Bead Filled (GF), Color: As Printed, Grey (Natural)
Finish: Vapor SmoothingParts that doesn't touch the oil was printed with:
Technology: HP Multi Jet Fusion (MJF)
Material: Nylon 12, Glass Bead Filled (GF), Color: Black-Dyed
Finish: Vapor Smoothing
There are set screw holes in the detachable cap as well as in the lens to nose adapter. They use M3 screws, e.g. "Stainless Steel Flat-Tip Set Screw 18-8, M3 x 0.5 mm Thread, 4 mm Long" (92605A098 from McMaster). They can be tapped with "Chip-Clearing Tap for Through Holes TiCN Coated High-Speed Steel, M3 x 0.5 mm Thread" (2605A21 from mcmaster).
To complete the dipping cap, we glued a window to the nose I.e. “Ø1" N-BK7 Broadband Precision Window, AR Coated: 400 - 1100 nm, t = 1 mm” (WG11010-AB from Thor). We used <> glue. But found that it can peel still so we also used epoxy. We will try using only epoxy in the future.
The 41mm nose is to be used with the SZX 1.2x lens. The 15mm nose is to be used with the SZX 1.6x lens. With the default tube lens, this would give an approximately additional 2x mag on top of the lens number.
The “detachable dipping nose” configuration uses a nose that threads into the lens to nose adapter. Then a dipping cap with the window is clipped on to the nose. The “single unit dipping nose” combines the nose with the dipping cap so the window is glued directly on the nose.
