Ok, so if I get the mechanics from those photos, their particular design has the flat square bracket (with the circular hole) which would be the plate which the mirror itself would be fixed against. This pivots on a ballbearing in the corner of the L shaped bracket, with 2 center springs under tension, which keeps the corner set screws under compression, allowing you to adjust the X and Y tilt, the L shaped bracket has 2 holes one in each "arm" which I'm assuming are for mounting the whole apparatus to your machine...<div>
<br></div><div>I'm not sure how the mirror is affixed to the flat plate with the circular hole, they mention plastic tipped screws, but I don't see that anywhere in the pic, but I might be missing that... Either way if my above assumptions of the mechanics are correct, I should be able to mock up a design for this quite easily... </div>
<div><br></div><div>If you have any other input to offer that might let me get something mocked up in time to show you tonight.</div><div><br></div><div>I'll confirm with my wife when I get home from work if tonight is ok for a quick meeting, and if she's ok with that then I'll email you and confirm timing and such early this evening...</div>

I'm in Bayshore... My house and workshop are a bit of a disaster area lately though lol... I think my wife would shoot me if I invited someone in right now :)<div><br></div><div>Either way, we could meet quickly to discuss your options, if you have some hand sketches or something of the parts, and bring along some samples, and dimensions, I could mock something up tonight/tomorrow, and we could discuss it more at the faire... your right in that there might not be a ton of time, but I was surprised how easily the design/testing cycle works now that I have rapid prototyping capability... Small parts take 20min to print or less, so I can easily whip up a design in an hour or less, print it, and take an iterative design approach to something that is normally much more monolithic... It wastes a bit more material, but since material costs are so low for the plastic filament, it's totally worth the agility gained in the design process...</div>
<div><br></div><div>Let me know what your thoughts are and we can talk about it. </div><div><br></div><div>I'm a bit busy tonight and tomorrow, as I also have some paperwork to catch up on for my home business, and some other todo items to deal with (I've been multitasking between print and other stuff) but I could probably afford an hour or so either tonight or tomorrow between 8pm and 10pm to discuss options. Otherwise we can talk at the faire and meet up sometime following that if that works better.</div>
<div><br></div><div>Even an email with some sketches/dimensions and pics of parts and so on might let me mock up something quickly if that's preferable as well.</div><div><br></div><div>Thanks!</div><div><br></div><font color="#888888"><div>

There will be several 3d printers at the maker faire, I would bet you could have mirror holders made at the maker faire with enough bartering/negotiating lol... 1" holding brackets wouldn't take long to print, it would mostly be design/testing time that would consume the most effort...<div>
<br></div><div>I'd be fine with printing them for you at maker faire for cost of plastic used (which would be minimal, hell I would likely do it for free depending on the volume of plastic). provided we have the time/resources to design the parts. I'm sure a lot of the other guys will have more Industrial Design experience than I do though.</div>
<div><br></div><div>Anyway, point being there will be at minimum 5 3d printers, and possibly as many as 7-8 at the maker faire. So between all of them I'm sure your parts could get done ;)</div><div><br></div><div>Also there is talk about kickstarting the RepRap Loaner program at the ottawa Maker Faire, so we will be trying to build a reprap mendel at the faire, and use it as a community loaner model.</div>
<div><br></div><div>I've been working on printing parts to have at the maker fair in the evenings this week (just for examples) so if you have a design in mind, or some info, perhaps I could run a few off as tests tonight or tomorrow, and bring them along, get a bit of a head start.</div>
