content: could anyone please print me a microscope Head adaptor ringi have a very old Nikon stereo microscope with a nice very heavy stand,the adjustable Head mount , has got multi angle adjustments, and i would now like to use it with my cheap new eakins c-mount hdmi/usb camera in place of the optic stereo head, the only problem is that the mount for the head has a diameter 62mm, it seems the STD/ now is 76mmand i can not get a adaptor ring any were, i have ordered a 28mm to 50mm ring from,https://www.aliexpress.com/item/1005001447360604.html?spm=a2g0o.order_list.order_list_main.25.21ef1802xXDuZRas the lens i got with the microscope camera has a shaft size of 28mm and it came with a 40mm ring adaptor and the stand is just a very weak microphone stand that shakes very bad when you have to adjust the camera,so if anyone can make me up this adaptor ring to go from 50mm to 62mm can you please let me know the price, and i will give some better dimentions, i am in the United kingdom i am now medically retired , so i can not get my own 3d printeri will be very great-full if some one can do this for meThanks Dave 2E0DMB

content: Have you tried eBay? I got an adapter for my Nikon stereo head to another stand for about $25 (Search: microscope head adapter ring). Here's another example:https://www.ebay.com/itm/204681511152?The older Nikon is a standard size, but smaller than most stands.

content: I have an older (late 1990's) NIkon stereo head. It was effectively unused. What is your model? I am sure your measure is accurate, but did you measure the correct mounting point? I will edit with a picture of my scope and hopefully a link t what bought. It was years ago.JohnEDIT:eBay's past history is a mess. I couldn't find that purchase.My ring (attached) is 62mm ID by 76mm OD with an 84mm rim. The little thumb screw on the side is helpful to keep the head from turning when adjusting the continuously variable magnification. It's not necessary, but helps and does not need to be tight.EDIT2:Amscope might have adapters too. I suspect you looked there too.

content: Have you looked at 3D printing facilities in your location?For example the Prusa website (https://forum.prusa3d.com/) has a section with international locations of individuals and commercial 3D printing facilities.A quick Google where I live has about 30 places that will either take a stl or gcode file and just print it and others will take a rough sketch with dimensions and do it for you.

content: Hi Johnthis is my Nikon microscope, the LENS says A.L.5 and the eyes are X10, There is no zoom, and working distance is about 200mm,i was working at bae when they closed use down, so i grabbed this as no one wanted it, i was only contracting so i had to give the perm staff 1st pickings, it is very very heavyDave

content: The whole optical path is involved in focusing. For example, one of the eye pieces ("oculars") looks like it has a small focusing ring so both eyes are in focus for people whose eyes are not exactly the same, which is very common. The "objective" is the lens at the end. It is most important for working distance. The power of the ocular/eyepiece times the objective = total magnification. Resolution is determined by the objective. For what you will be doing, that distinction between magnification and resolution is probably unimportant. With variable magnification, for that type of microscope, one must usually refocus when changing magnification. Your scope will be fixed.Why do you need a new stand? That is a nice stand. If you were closer, I'd gladly trade with you.

content: Hi John,i picked this up about 25 years ago, and it has been very useful ,No John i will be using this stand with my HDMI/usb , sd card video /Photo Microscope camera, as the stand i got with that one was very week it is a cheap microphone stand,as when i will be using the nikon stand with the HDMI camera, it will not move about, as this is very heavy and solid, it does take up more room on the bench,so this is why i need a adaptor ring,i have sent Nikon a email asking for any info, it will be good to find out the age of it,also do you know anything about the adaptors that you remove the lens eyepiece and put a c mount hdmi camera in its placedo these adaptors have a x10 lens in place to make up for the one that was removedThanks Dave

content: Quote from: richnormand on April 06, 2024, 09:48:28 pmLol, I set it to print and then watched some TV while I waited for it to print. I now have a birds nest. I think the ABS came unstuck from the bed. Will try again today, it's only a 1hr 45m print.In other news a new Klipper based board has turned up for my machine so once I have a good print I will take my printer apart to fit the new board. Then I might be able to use a half decent slicer.

content: Hopefully it will work this time, I had bed adhesion issues. I just made some Acetone-ABS slurry and smeared that on the print bed and that has stopped it warping. I also dropped the temp by 10C as that was at the 270/280 range and my abs is a 240 to 260C stuff.

content: It is not that bad, I don't use mine a heck of a lot and like anything, some problems come up just from the nature of what you are working with.ABS needs to be hot to melt, it's stronger and longer lasting. But as it cools it shrinks and depending on the shape that can cause it to come unstuck from the print bed.I have used mine a few times to make inserts or brackets for bikes. Even made a part for a Morgan +4 as the gearbox part is no longer made. I had the part modelled and printed within the weekend and the car was on the road the following weekend.

He occasionally had to tighten the screws. A dream car for me.Sorry for the OT. I couldn't resist. Gorgeous real car.

content: I bet it is very handy for parts you can not get anymore,i bet when you got it , you were trying to think of things to print,and it is good it is getting quicker to print things now days,but you do have to know how to set it up,i think a lot that get them use pre made files,a wile ago i helped another ham on the FT-817 group, set up his data interface, and he said that he had a 3d printerand if there was some thing that i needed, and i asked him to make a soldering iron tip holder, as i have Metcal irons ,and he told me to look on thingiverse, so i did and found one in seconds, it is a great site, the stand was for a different make so all i had to do was open up the holes about 0.5mm,Thanks again Dave

Will try some PLA tomorrow. Don't normally have this many issues but I will get there. I have got a 37mm high print though, just 6mm (20 layers) that it missed.

content: Considering this is for a microscope (inside gentle use I assume) black PLA would be my choice.I mainly use PETG and PLA. That fills about 90% of my uses. PLA is the easiest to use and has good adherence to the platter when cleaned of oils.I reserve flexible and carbon (for SEM holders) stuff for special applications.I also found that problems with the 3D printer are usually when it is idle for a few weeks or more.The platter needs to be cleaned with dish soap (non perfumed like Dawn) and the filament purged in the extruder and the filament spool dried up in the humidity controlled oven even if left in the bag with a desiccant.Otherwise I get all sorts of issues.Fortunately I use mine two or three times a week for the car (old Miata), pool, bathroom, garage, electronics, lathe test parts, etc...Many people don't realise they would use a 3D printer quite often if there.Both were gifts from my wife (Miata and 3d printer)

content: I managed to do it!ABS, came unstuck.PLA came unstuck.Cleaned and cleaned,PLA didn't come unstuck but ran out of PLA.Stripped head down to clean.PLA snapped after 3 layers as the new reel is heavy and didn't want to roll nicely.Sat there with YT vids, manually rolling the reel to prevent snapping.Printed.3D printers are like test gear, great when they work. Damned annoying when they don't. I will post the part at some point, Dave, I was hoping to go for a bike ride but people want me to be Social this weekend, it's what I get for getting older I guess.

content: Its in the post. I feel lazy getting the postman to pick it up.Turns out Post Office recommends Evri and DPD for parcels, then wants to charge a good portion of an arm for it. So I went direct to Royal Mail and it was a lot cheaper and he collected it today while I was at work.I sent two parts, the ABS one that didn't fully print but might work. The other is PLA and it is the right height. I printed it with two layers on the wall so you can sand it down if you need to adjust the fitment.

content: If you are concerned about the pressure of the set screw you can heat a tack or small nail and press it into the adaptor at the appropriate location. The head of the tack will spread the load over a large enough area to eliminate any serious concern about the set screw pressure. Drilling a small hole in the plastic adapter prior to installation of the tack will make the process easier. You can heat the tack with just about anything - a soldering iron, a candle or whatever.
