Well, FedEx actually came through and delivered the H2C yesterday! I had been working on a couple models most of the day prior to delivery, so when it came, I unpacked it, set it up, and printed my models. Here's one (the light colored one), can you guess what it is?

Yup - a spare tire bumper. Still learning all the settings, so that's just with the default settings. I'm going to try printing it with a TPU top portion eventually - this was just a trial run with PLA. It'll have a steel insert (a repurposed type H drill bushing) pressed in so that the screw doesn't fracture it. I'll be posting more info in my build thread as I make progress.

I'm very pleased with the H2C. What a fun tool! Jeff, when Santa brings you the H2D, you're gonna love it!

Since the H2C arrived a week ago, I've immersed myself in the technology of 3D printing. I had to learn a whole 'nuther language! Also, I'm finding that many of the designs available on the various sites don't meet my standards, so I am designing most things I print from scratch, which takes a lot more time. Following up on my previous post, I've figured out multi-material printing and TPU printing (not as simple as other materials). Here's my finished spare tire bumper with a plug for the end:

I used PTEG HF for the main portion, and the top and bottom are TPU 95A HF, and I really customized the slicing. The top was TPU for some give against the tire, and the bottom was TPU because it works with the plug to seal the bolt and sleeve inside from the elements. Both filaments were thoroughly dried prior to printing. The TPU got slightly stringy on my at the very end of the print.

I plan to post more about my design process on my build thread when I get a breather from 3D printing.
