First 3d printer - Ender 3 pro
Joules:
Nice to see more printers being acquired and used by MadModders. Out of interest, if you want the maximum performance from your filament, pick natural as it contains no pigment. The pigments contribute nothing to the performance of the material. That being said, white is my preferred for outdoor applications and natural for components not on view. I have done quite a bit of work making hybrid parts, inserting Delrin or metal where parts are in contact and need to slide or act as a sear or bearing
They are a fantastic tool for prototypes and speeding up product development, or even production parts in their own right. I hope you all thoroughly enjoy your printers.

Hey Joules,
Is there any way to print stacked parts that move relative to each other without using dissolving filament? I've tried spacing them apart but my slicer won't print supports in the gaps. I ticked the 'anywhere' box for supports but I think the gap is too small to be recognised as a gap, either that or the slicer doesn't 'see' the space between two solid models.
Joules:
Pete, you have to start designing your own support that can break away so captive parts can then move. Takes quite a bit of experimentation as filament that isn’t properly supported can droop and weld to the near surface. This is mainly why I design as separates, print then weld the parts together using a temperature controlled iron.
I find quite often that auto generated support isn’t very adequate in complex designs, hence design it into the 3D model rather than auto generate. Think tree structure and 45 degree branches or single (0.4mm) support shell if that is your nozzle size. You just need to be able to get in and snap it away.

Cheers, I kinda figured I was flogging a dead horse.
Well, here's my first 3d printed working model. It's a Balzer cutter relieving attachment. Does the same thing as a Eureka machine, if you know what one of those is. Some of the parts have printed a bit rough due to the raft leaving a cross-hatch pattern on them but other than that it's fully working on the hand-crank. I took the details from the original 1895 patent.
I wonder what old Balzer would have thought of 3d printing, back in the day?
Kinda chuffed with this as up until 4 days ago I hadn't even seen a 3d printer in the flesh. This has three gears that mesh, but one has two different DP on the same gear and the small gear has a different pressure angle to either of the big ones :D

You have every reason to be chuffed!
