Retra Maxi Bumpers and stuff

Featured Replies

Does anyone have a file(s) for printing bumpers for the new Maxi strobes?

As you guys coerced me into buying some Maxi strobes I find that currently Retra has not caught up with the Maxi product accessories, it needs bumpers!

I assume that Retra will eventually produce bumpers? I think they told my wife that they were in work.

I've made bumpers, reduction rings, and improved knobs for the Retra Maxi strobes. You can find these and other UW photography accessories I've made here:

Thanks for the info. I looked at that site but do not understand, do I order from the site or download? What is meant by Plate 2?

I have used JawsTec to print several dive related and other items in the past, most recently G250 bumpers.

Edit, oh, I see, think I figured it out.

Makerworld is not for sales, it is a free sharing site for 3d printed designs. If you can't print your own items, message me and I can send you what you want for a reasonable cost. I generally charge the cost of a spool or two of filament plus $10 shipping.

Dave,

If you could that would be great. I have used JawsTec with no real issues but I would rather send money to a fellow diver and you know exactly what they should be. And they are kinda slow, I have another trip June 22nd I think it is.

Let me know, thanks,

James

I got my bumpers and knobs! Super Nice!!

About the standard Retra knobs. They have a cavity inside that could hold water and fit so close to the case that blowing out the water completely might be difficult. In replacing my knobs with the 3D printed Super Nice knobs, (1) I discovered that the shaft itself is Nylon, not stainless! Hmmm, I did not expect that on $XXXX strobes! (2) The cavity seems to serve no purpose and I took a 1/8 drill and put a hole in them into the cavity in exact alignment with the set screw hole such that it intersected the cavity at mid depth. (3) JFYI, the set screw goes deep into the plastic shaft and must be nearly completely backed out before the knobs will slip off the plastic shafts.

I am quite certain that the added hole would allow complete rinsing and removal of any water and since all the parts are plastic I am not sure it matters. But who wants salt water left in their expensive gear, so add the "blow" hole or get some printed knobs that do not have the cavity and have a small gap at the interface to the back plate to properly drain.

Hey, Retra, what is up with those plastic shafts, are those going to snap off? My Inons have plastic bodies and metal shafts, my Retras have metal bodies and plastic shafts, this is making my OCD hurt my head!

On the first moon landing, Armstrong hit a CB switch accidentally and broke it off. If not for an ink pin inserted into the CB they might still be on the moon. The point being, if it is important and can break off, it will, exactly when you need it most. Plastic shafts? Are those going to break when I get that whale shark in my VF?

Very slick!

About those original knobs. I shared with Retra the feedback about salt constantly forming around the knobs even after an overnight soak. That hollow cavity and tight fitting to the base means they just can't be rinsed out.

I designed the replacement knobs to eliminate the cavity and provide a slightly bigger gap at the bottom to allow for drainage. The mode switch gets a different shape to make it easy to distinguish with gloves on.
