Yes I cover the ring with epoxy The other part are printed with 70 % filling and wall thickness 4 or 5 pass. If some water get in it is not a problem.. if a piece break It's visible and not break directly complet... it is easy to build a new part Putting epoxy is possible but bring some dimension problems to fit the parts together.

With this setup I'll be able to use my RF100 make some super macro with the SMC-1 If needed put the MFO-1 (80 % of the macros shoots during the last trip) or if there is a bigger subject switch on the MFO-3....

I forgot a point, I removed the rubber on the MFO-3 (like I made on the MFO-1 and SMC-1) to block firmly the lens beetween the to PTEG parts.

Don't hesitate to ask if you have some questions. Hugues

Details of the lens/port jonction. The thead is protected. The lense didn't touch the glas of the port, it is the holder who touch the port, but not the glas.

the final version will look like that

for the MFO-3

Some test

I found a picture of the black version with 2 binge

I was lucky with the first solution... then the two hinge was perfectly positionned on the ring to give me the possibilty to put a third in the middle I build a part with 3 hinge. and on the opposite 3 hooks All lenses can be put where I want. The idea is SMC on the left MFO-1 in the middle and the MFO-3 on the right. Ich it's no ok I will switch the MFO depending on the result underwater.

The idea is to put 2 rings (in gray on the picture) printed with TPU the only risk ist to lost the MFO-3 ...

first I need a holder for the MFO-3 The other part I build in the past I put the 2 pieces together with screw. thi time I try something else

Since the first version I made a second in black and a second arm for the MFO-1 and a little bit bigger ring to have more buoyancy I was really happy with this solution Now the problem I didn't have a lot of time before our holliday... I need a simple solution

First version mounted

The SMC 1 to show the principe
