What 3D printing project are you working on today?

[Epatcola]

Today I worked on a jig to attach the CR30 spectrophotometer to an old ender 3 clone printer I have.

It works pretty well although I still have a bit of tweaking to do. The build plate is 220mm square. I can't use all of it because the CR30 sits forward of where the hot end was. 26 rows and 28 columns of 7mm square patches is about as much as will fit on the plate and A4 paper. It took 23 minutes to measure the 728 patches.

I posted the initial idea here.

Today I worked on a jig to attach the CR30 spectrophotometer to an old ender 3 clone printer I have.

I finished tweaking the g-code and got it down to about 17 minutes to read the 728 patches.

I was using the CR30 bluetooth interface which proved to be unreliable randomly missing between 2 and 5 patches of the 728. It didn't miss any with a USB cable connection. The PC bluetooth is provided by a modern Intel wireless chip set and has an external antenna so you would think it should be good and the distance was around 10 feet.

Annoying because the bluetooth connection is convenient. I don't see why manual reading over bluetooth would not have the same problem and having to check that the PC got every measurement is tedious. If you are using bluetooth and notice you didn't read enough patches it might not be your fault.

A few seconds of video here. It might not stay hosted for long.

It's amazing what people are inventing!

This guy does a new invention every day (which goes along perfectly with the theme of this thread), and some are lame and some are pretty cool. This one is pretty cool.

I've only had my printer for a couple weeks. My projects are mundane. Here's my new Sensitive Weathervane:

The slider has two circular pockets that accept one or two US nickels. That lets you balance the assembly; it spins on a single ball bearing. The blades are dovetailed into the center post.

That's actually pretty cool, and the type of print I love!

You designed it? If so, which program?

Yes, entirely from my warped brain. Simultaneously with learning to print, I'm also learning Freecad 1.0. It has its quirks, but I don't hate it any more or less than the Solidworks we use at work. As soon as I get my files in order, I'll put it up in Prusa's printables area. Not because, as suggested elsewhere, that I work for Prusa, I don't, but because it is on the Core One. And it's orange!

Needed to mount these:

to this.

So I whipped these up in tinkercad and printed them in PLA. I wanted them to be a bit more durable for use outdoors, so I ran them with more wall/top and bottom layers and 40% infill (vs my normal 15).

They've got a knockout on the back to accommodate the tripod leg, and just strap on with some velcro cable ties passed through to the front. The battery and intervalometer are then attached using more velcro.

Now, we wait for a clear sky to test the rig.

I have been using my Creality 3D Max printer for several products like boxes for batteries, containers and craddles for repeaters/mobile phones. But the most economical savings was for my microscope:

This adapter costs an incredible amount of € 161:



For just a cylinder to connect my Motic BA310E microscope with my Canon RP full frame camera, so I printed it myself for a fraction of the price:

Another thing is the dark field slider for a whopping €121:



So I printed this myself using the dummy holder that closes the hole of the condenser as a mold to start from:

This is the effect of the dark field adapter between normal (bright field) lighting and secondly dark field lighting:

Way to go pharmacist.. glad you’re on board with 3D now..
