To encourage and assist amateurs interested in making 3D printed spectrographs, we will prepare a web sub-group for them.
There are at least four concept designs being discussed - Paul's "LowSpec",
John's "Littrow", Christian's "UVEX" and Tony's "TRAGOS".

You are more than welcome to visit and check out this exciting new development in amateur spectroscopy.

      Would anyone with 3D printer experience care to give an opinion on Aldi's offering of a 3D printer?

      Hi All, just thought i would show the results of a little project.
      I have been guiding with my Orion Mini Fifty with great success using a ED80 F7.5 scope to image through.   recently though i wanted to get a little closer to some of the objects coming up in the summer sky.   M13, M3,  M33, M27, Cygnus wall, m101, wizard nebula... etc etc the list goes on.  
      I will be trying with my 2x barlow giving a focal length of 1200.  Which should be OK guiding with my mini fifty, but i wanted to try and match the pixel ratio a bit better to see if it helped, BUT i cannot get focus on the mini fifty when i use a 2x barlow on that...   i can screw the barlow lens directly to the end of my QHY5ii_L mono but the focus point puts the camera about 1mm out of the back of the tube.   TOO CLOSE to use a barlow as an extension tube because of the internal shoulder.... hmm dilemma.   
      Now i am a product designer so to the drawing board i went....well to Sketchup anyway.   Money is always tight so an aluminium turned part was out, but a rigid plastic 3d printed part was on the cards.     And as luck would have it, my work bought a new SLA 3D printer (Form2) from form labs) capable of printing to 25 micron resolution.   I thought Christmas had come early!
      attached are images of the final part attached to the rear part of the Mini Fifty, ready to be screwed in place.   Not sure how i managed it but i got the tolerances right first time....and measuring the rear part with a ruler. 
      fitting diameter to slide over the rear part of the min fifty = 42.25 diameter.
      fitting for the camera (1.25") = 32.5 diameter.
      as you may have noticed i will need to add 3 x M3 threaded inserts to the back end of this to clamp the QHY securely in.   i can post images after this is done.
      if anyone wants this model i can provide it.  None of the internal/external detail is needed really, but this was to see what the Form2 could do.   And i can say ........it is amazing.  (for everything but closed cavity printing.
       
      clear skies everyone.
