The Kits Initiative is looking for 3-D printing enthusiasts to help us source parts for the Basic Microscope Kit!

We're investigating possibilities for sourcing the 3-D printed components of the Microscope Kit (coming soon!) and are interested in seeing if there are community members who might be interested in contracting with the Kits Initiative to supply some of these parts.

The print files can be found below:

If you think you might be interested in pitching in, drop us a line at kits@publiclab.org so that we can discuss price, timelines, etc!

I posted this on Thingiverse too! https://www.thingiverse.com/thing:2820427

There is one part at Thingiverse. Is that the only one you need printed?
The part at Thingiverse has a flat horizontal lower surface which could cause the print to fail on some printers.
I would be happy to print five of these for free if all nine of the other Replicators distributed by Public Lab did the same.
I would also be happy to print 10 of these for free for every one of the abandoned Public Lab Replicators that is shipped to me.

There seems to be a small piece that sits under the camera too!

That would be amazing, Chris. I echo your idea of getting some of the other Replicator recipients to chip in here!

Richard from OpenFlexure has proposed this piece, although I'm not sure it's compatible with both cameras -- https://github.com/rwb27/openflexure_microscope/blob/master/builds/optics_picamera_2_pilens_SS40.stl

I noted this image for where we need to add some extra clearance:

Chris, would you print us a few even absent other donated Replicator teams chiming in? Do you know who else has one? Maybe @danbeavers -- i think I remember he was doing some printing!

Although that's not the right piece -- we actually need the wider adapter; i think Richard was just saying he thought the camera interface was modified, but I don't think it actually does fit the v1 camera yet!

If that model is modified to allow for the components and the ribbon, it should be done so the new underside surfaces are not horizontal. FDM printing can choke on large horizontal underside surfaces unless they are the very bottom of the piece. The existing flat horizontal surface in your image (southeast of the rectangle annotations) will not be printed gracefully and should be sloped or domed.

The last known locations of the other Makerbots are listed here: https://publiclab.org/wiki/makerbot-machine-logs. If any of these are no longer in use, I would be happy to pay for shipping a few to me or print some parts in exchange for shipping.

Just as a price reference, Thingiverse offers a kind of crowdsourced printing service and various services seem to offer about $12 as a quote for the adaptor.

NinjaPrototype charges $4.50, but then $25 shipping. Maybe it'd be more affordable in bulk -- yes, $70.50 for 10, or ~$7 each.

@j-bower -- Richard Bowman has taken a stab at a combined lens mount for v1 and v2 cameras! https://github.com/rwb27/openflexure_microscope/issues/71#issuecomment-382080106

@j-bower, thanks for offering to help print these!

Of course! Thanks for the link, and thanks Richard!

I heard you also have a lasercutter? These new files for the stage can be cut pretty easily by hand or by lasercutter -- would you be able to send us a few? We're sending you three webcams, bolts, tape and wingnuts so you can build your own:

Chris, you're welcome to some parts as well if you'd like to get involved!

Also noting this great photo from Richard:

Yes, for sure. I need to double check on the plywood I have lying around - pretty sure it’s 1/4 inch. There’s also lots of scrap. I noticed you listed 1/8-1/4 on the page, does that still work?

I think it will work! It doesn't seem like the width of the stage is that important.
