This is the anodizer bath that I originally posted on Linkedin. I modified it recently to accomodate support-free printing in a Formlabs or other SLA or DLP-SLA printer. Jetted photopolymer should also work. I do not know how this will behave in an FDM printer, but should work if your printer prints support material..
If you print it, please post to that effect on Linked in; include "@Tim Hart" in the post. Thanks!
SLA: I recommend post process UV, even if you are using a resin that does not require it. Since the model has several areas in "the shadow", run it in the UV light with differing upside-down orientations.
Slightly Parametric // You just need a nut and a screw to complete assembly
This was designed in Openscad (.SCAD file included in the downloads), and you do have the ability to modify several aspects of it. The tall tube is for holding your cathode, it can be eliminated. Likewise with the "screw-down" lugs.
The anode slot is meant to accept a #8 hex nut and screw. Once you install the nut, you will be able to utilize the screw to secure (and connect) the foil into the slot, as well as use the head of the screw for your alligator clip.
