NSD 2005 Oil Seal 1.5

I did a quick test print on this at something like 10% infill, .3 layer height, which took about a hour & that said I hope this doesn't come across a negative review, it's more of a impression from comparing both an original seal & printed part with a 100mm hemi & not being totally happy with the overall look of either.

Personally I prefer a more circular shape than hexagonal sides, I made this mistake myself on my first printed NSD dome light cages not realising I could set the number of faces in Sketchup. That's the only thing I from a Dalek point of view that I didn't care for.

The diameter is correct when compared to a genuine oil seal, but the height is a little over, so I'd reduce this by about 2 or 3mm.

The 100mm hemi fit's snug against the ISD, gluing in place would be a sinch, but when compared to the original seal with its middle lip, the hemi looks undersized\seal looks oversized in relation & under detailed. That said I'm not wild really about how the hemi looks when inserted into the oil seal from my pictures it looks too bulbous. - What I personally would do to compensate would be to reduce the diameter slightly & create a solid outer ring that holds the hemi captive between the two surfaces & would make a nice glue channel.

I went for the reduced infill on grounds of expediency & the fact that the part is mostly detailing not load bearing, that said I would consider increasing the height of the four support struts & the nut chamber floor by another mm at least to give a little more overall strength (I didn't print a raft) especially when the screw needs to pull against the skirt panel twists to fit flush & possibly go for three or two struts especially as that would give increased finger access in the event of nut loss, It may even be possible to import a printed M6 thread in a later revision.

I can't after taking pictures post them alas, but I will find a home. In closing given the time taken for printing one of these making a mold ideally would be required.
