You can save so much money with CAD if you neither factor in your time to actually learn it or the cost of the printer itself.
Makes crime even better in comparison.
Learning a new and useful skill is not "wasting" time at all.
Someone else I know got a printer and got bored printing with it after a bit and said I can print on it whenever if I toss them a roll of material every now and then.
I ended up finding all kinds of useful things to print. I made a connection piece for a sink that had a garbage disposal removed when I couldn't find the fitting anywhere and after 3 years it's holding up fine. I made a set of cams for a washer that randomly stopped spinning one day and those have been working nicely. Just a bunch of times it ended up coming in handy.
The saving on the knob alone would pay a reasonable chunk of a basic but useful printer. Use it for a few more things and you'll be in the black even ignoring the more fun things you might do. The time it takes to learn a CAD system can also be fun if you enjoy that sort of thing.
I'm proof. My first printer is currently worth like $25. Maker Select V2. Still works great. I learned FreeCAD and enjoyed every minute.
As someone who replaced his Maker Select Plus with a Bambu Lab P1S a few months ago…if you do get a new printer, be prepared to be angry for a moment.
I spent so much time and effort improving that thing over the years, and the modern printer was so much better right out of the box. 😅
(Not that I don’t still have a fond place in my heart for my old bedslinger. A friend has it now, so it’s still chugging along.)
compooter + printer still go brrrrrrrrrrr
My printer has saved me more than its cost in useful stuff I have printed.
Here in Canada every major library I've been to has a 3D printer you can use, either for free if you bring your own filament, or for a very small fee to use theirs. I live in a small town of 70,000 people and our public library has a 3D printer.
I would just like to say that 70k people isn't a small town. I live in a town with 9k people in it. Now that's a small town.
Only 9k people? That's not a town, that's a village.
/s
9k? That's a major city. I lived and worked in an area where the 9k town about an hour away was the bee's knees for the folks where I was, which had a great!!! city of 2,500, and the rest were unincorporated places of a hundred or so at the crossroads.
Shoot, I just moved to town under 1k.
I have wasted a bunch of time making things, but like woodworking or similar trades, it's fun and rewarding.
Hence, why it's not "wasted" time.
There are places which will print out your model for a small fee on their own printer. There are even places which will allow you to use their printer if you come with your own filament (for example makerspaces) and maybe donate a little bit to support them.
As for CAD itself, there's a nonzero chance that someone already designed that part for themselves and you can download a ready model. If not, then by designing it yourself you're acquiring a skill that can be useful again in the future and you can share that model with others to get that warm fuzzy feeling that you've helped strangers who had the same problem.
