Designing new models takes time and filament, among other things. It's not enough to just model something, I have to print it and make sure it actually works/fits/durable.
Not everybody has money to donate, so I won't ask for your money. But what you can do that is absolutely free is install and sign up for Temu using my associate link below:
Not only can you buy 3D printer items and parts needed to make my designs, you also get a really nice discount (30% at the time of this post). Temu ships pretty quickly, the prices are really low, and the quality is very good. The credits I earn from referrals help me buy filament and publish more free useful designs.
So if you can, please take a few moments to register for Temu with my link. I personally use Temu to buy most of my filament and printer parts unless I need something in a hurry (in which case I use Amazon). Temu does ship faster than AliExpress with prices that are pretty close. Amazon usually costs about 3-5x as much, but I get it in just a few days. Usually I can wait an extra week to save a lot of money.
