No. That is a cosmetic effect and we need a fully functional part that is properly amalgamated right through the thickness.
Fair enough. But I will use Nylon and that will be non-permeableI was thinking more about washing the inside to create a non permeable surface...
ARe you doing two pieces to simplify printing?Some more pics.

No. It would be a backward step, just adds difficulty later when it comes to joining the parts.... I am confident that one part print is doable.ARe you doing two pieces to simplify printing?
3-D printing constantly reminds us that everything we've learned from subtractive machining is wrong....No. It would be a backward step, just adds difficulty later
The PLA sample does hold water - at least for a few hours so far But it is only a draft print with thick layers and a non-functional material. I expect no issue with proper materials and performance rather than speed print settings. I will bench test fluid retention of course. Any item that won't hold water will not have adequate inter-layer strength anyway.It would be worth filling the white PLA sample with water and seeing if it weeps. I have problems in the past getting 3d printed materials to hold water. I suspect you might hit a similar problem with any fluid in a 3d printed container.
which materials, settings etc? Very happy to learn from the experience of others!3d printed materials
ahahahahahaha I have 4 cars that are fully dissassembled by others.... It will fit exacty as the OEM item does as it is dimensionaly identical. I measured an OEM item in the first place. I will see if I can find a bracketHow does it look to fit in the mounting bracket in the car? Do you have a car with no brake fluid reservoir to check it on?
Actually, I have a 78 awaiting restoration that is complete [been sitting for more than a decade before I got it]. I will do a step by step take the OEM setup apart and rebuild with printed parts. Will be a useful exercise.How does it look to fit in the mounting bracket in the car? Do you have a car with no brake fluid reservoir to check it on?
as in fill with brake fluid and set it aside for a month or so?I will bench test fluid retention of course.
I left the wide flange around the top off and also the low level line purely to reduce print time [came down to 14 hours from 20]. The wide flange is the original joint in the OEM item which was made in two parts.
Going by my very poor memory, I believe that flange around the perimeter also acts as a 'rest' for the mounting bracket, to prevent the whole reservoir from slipping down too far.How does it look to fit in the mounting bracket in the car?
Matches my memory as well. The bracket is a belt around the slightly narrower waist.Going by my very poor memory, I believe that flange around the perimeter also acts as a 'rest' for the mounting bracket, to prevent the whole reservoir from slipping down too far.
Yes, exactly. I think I will do some sort of over pressure test too. These reservoirs never see pressure but it is a good way of checking integrity.as in fill with brake fluid and set it aside for a month or so?
Just left these features off for the PLA test print. Intent is to produce a part in the engineering materials with complete OEM geometry. That said, I reckon these are routinely installed incorrectly. My intact 78 has this reservoir installed as you describe. nSitting down in the bracket with the flange preventing it from sitting any lower. But. If you look closely at the reservoir and bracket, you will see that on the short ends of the reservoir there is an obround protrusion and there are matching slots in the bracket. Clearly, the reservoir is designed to be installed with these protrusions captive in the slots. Installing like this [as designed in my view] also means that the ridge around the centre of the reservoir is above the bracket and thus visible - which it needs to be as it is the minimum fluid level line. This ridge is quite large and it sits against the top of the bracket too.Going by my very poor memory, I believe that flange around the perimeter also acts as a 'rest' for the mounting bracket, to prevent the whole reservoir from slipping down too far.
You are thinking of the clutch reservoir I reckon. That has a distinct narrow waist and its bracket is a beltMatches my memory as well. The bracket is a belt around the slightly narrower waist.
