- I am going through the steps I took to make a large format camera adapter adapter for my polaroid camera. Usable on Polaroid 110a, 110b, 900.

Hi Nicolas! Your design looks great, truly an impressive job. I was wondering of the parts are available to download? The thingiverse link in de description is broken, and only the front part I can find. I don’t mind the painting an glueing myself. Anyway, keep up the good work!
as the other user said, the link sadly is broken so there is no thingiverse page for the mod sadly, i hope it can get back online because it looks like a really good mod to do!
addition to the comment: i noticed the camera has an engraved name on the top, do you know for what reason it is there? i own a 110A and it has engraved letters and i was really wondering why it has so, and the font and look is basically the same as your camera, if you know anything about why of such engravings i would love to hear, thankyou so much
Great job!
Looks amazing! Good job, new part looking like factory fresh one. Can you tell how long it took to print using sla printer? Peace
How did you make the front standard so it can fold and unflod ? The metal parts on the sides have many empty spaces.
The front standard can rotate like the original. I just copied the original and used 4 pins, 2 pins for the rotation and 2 pins that gets clamped in position like the original design.
@@n.defrance How do the two fix in position and then retract? I don't really see. The original had a spring. image.noelshack.com/fichiers/2023/42/4/1697746682-image-2023-10-04t17-14-25-984z-1.png image.noelshack.com/fichiers/2023/42/4/1697746672-image-2023-09-24t19-47-07-801z-1.png
The back springs is the only thing that I could not replicate, too much pressure. The back 2 pins are the pivot. the front 2 pins are smaller and do not stick out sideway as much, they barely come out past the metal side plate. When I push forward they are clamped.( I have kept all the clamping assembly of the original lens.) I just copied the original lens.
@@n.defrance OK thank you for the explanation, so it holds in place by a light pressure on the sides of the front pins. Did you use the weird shape hole for the back pins axle and the front pins ?
How did you grind the cam ?
I made one in 3D for a 150mm lens, and I ordered a copper machining and a copy in 3D print but the accuracy couldn't be better than 0.1mm. I wish it could be 0.05 at least.
I used the original back pins and I inserted them in the 3d print, That was not a good idea and I should have made some new one. For the front I made new pins of the correct size and glued them in the 3d print.
I made a cam from a piece of metal because I wanted to keep the original one intact.
I adjusted it by focusing in the ground glass at a certain distance fitting the cam at the same spot and taking it off and filing it with a flat file until I had the correct focus in the viewfinder. Repeated the process at different distances and smoothing in between.
After I checked everywhere and adjusted until it all matched.
That took the best part of an afternoon.
Do you sell the back ready printed?
No, I don't, sorry.
But I have been thinking about it. This one right now is more of a prototype. In its current form it is too time consuming to make.
Why would you use a very sharp high resolution camera with an inferior instant film? Every instant picture has low dynamics, bad colors, low resolution.
I will be using it just for 4x5 film.
The grafmatic film holder is a 4x5 negative film holder that can hold 6 negative films.
