The battery holder is obvious but I thought I would try something simple like a key tag. It took me a while to get the code right (you have no idea the angst caused by a missing “;”) but eventually I was able to print different styles as shown in the pic. (I got the idea from the Internet)
OpenScad is free open source software which uses basic shapes to create quite complex objects but naturally I am still at the simple stage. If you look on YouTube you can see very complex designs create using it.
//Key Ring Tag
//number of sides or resolution
//Text is flat so has to be given height
#text("TC 92 DO");
I think it is amazing that so few lines can create such a 3D object. Fortunately there is a Cheat Sheet built into the program which I refer to a lot (and I mean a lot)
It is surprising how the filament lasts - I am still using the 300gram roll supplied with the printer
The little boat in the thread you showed is a very common test piece I have come across before, it has lots of curves and overhanging pieces. It was an interesting thread to browse. I think the 3D printer shown is far more sophisticated than mine - mine only prints to a maximum of 150 by 150 by 150 (mm) very much a beginner’s model.
I have downloaded a Buddha from Thingiverse which is identical to a ceramic one I have and I might print it when I change the filament for a full roll. However I don’t have much interest in printing figurines or the like but I do want to be able to repair stuff when a plastic moulding breaks for example. However at the moment I am printing junk to get used to the machine and learn Openscad, just created a right angle bracket in the latter (another very small step)
Honestly, these things concern me. My grandson has one and has made several bits and pieces, most of which were just for fun, not for real application. And I just find myself asking, does the world really need all this extra plastic? I thought we were being urged to reduce our plastic usage, and these printers go utterly against that ethos.
That is a good point, Sheba, and its something that should be investigated. Apparently there are ways to recycle the plastic, but its a huge faff and would put a lot of people off. Plus you need extra tools (like a filament extruder) which adds to the cost, I imagine. So, yes, more effort should be put into trying to find ways of recycling this stuff - as useful as it is.
You are doing really great at it, and you’ve picked it up so quickly! You’ve definitely made me think I’d like to have a go when I retire
My model railway friend has made me some useful bits. ( and it will be handy having a bit of an expert for advice!)
The knob on my cooker split and he made me one that matched exactly in black and also a drawer handle on our bedroom drawers that had been discontinued. He made it in white and I painted it to match, it looks OK, much better than an odd one
I think having someone to guide you through the very initial stages would be a great asset. Unfortunately I didn’t know anybody who had one but I found a group on FB who helped a lot but being shown would have been great.
It is turning out to be quite fun. I must admit learning the coding interests me anyway.
I was surprised to discover only today that there are free 3D scanner apps for a phone. I think one was called Copycam (that might not be exactly right) but I saw a video of some one using it on a full size bronze statue using a selfie stick to create a very accurate model. It was very impressive.
Likewise the child’s drawing, again, within the last week, I have seen a video on how to import a 2D computer scan/drawing into Openscad - I forget the file type but it is one used for graphic design in free programs like Inkspace.
The possibilities seem amazing once you start looking into them, using equipment you already have and free open source software.
