    Alternative Parts

    So unfortunately I didn't see the discussion on the replacement header before I placed my order. Here are the parts that were unavailable to me yesterday and the parts I chose instead. Anyone see issues with them? I think everything will work, but someone more knowledgeable might save me some headache before I go to solder it together when it arrives. If these components work, we can update the wiki with additional alternatives too.

    Those should all work fine.

    Thanks Steve. I'll confirm once I've built my first HM and verify this!

    All of those components did in fact work as expected. Do you know if the wiki is something anyone can update or is that controlled by Bryan?

    Anyone can edit it I think but I've just made the changes with the alternate part numbers. Does the 1TA suffix on the capacitor mean that it came on a piece of paper tape for feeding into a machine?

    And thanks for finding the parts and reporting back, I'm sure those will be helpful for others!

    Based on the datasheet it looks like 1TA is some type of taping code, but I'm no expert!

    I've published the updated 4.3 case with support for Pi3A+. There are also a couple of minor changes:
    • Raspberry Pi 3A+ option
    • Less round nuttraps for straight-only overhang. The old nuttrap tops had their corner radius extend over the insertion holes, which meant it was not only a bridge, but the curved part was unsupported as well. Now the curved part is supported and the overhang is a straight bridge which prints much cleaner. The old curved corner would just be a blotch of drippy filament.
    • Corner radius now a function of wall thickness for consistent thickness at corners. The curves were always 4mm radius before so the thickness of the wall along the curves would be inconsistent for any wall size other than ~2.5mm. It now scales with wall thickness to stay roughly "wall" thick through the corner.
    • Removed pin cutout by LCD. The LCD pins are even shorter than the shift register pins so there's no need to make extra space for them. Even if the pins are inserted completely incorrectly, they can still be snipped off to fit without the extra space in the case.

    Hi guys,

    I just got a 3d printer and after a week of getting my feet wet printing mods for the printer itself (Ender 3 pro), I'm ready to tackle a bigger project - reprinting the case for my HM 4.3. My old one was black PLA printed by another board member, and as Bryan mentioned, it absorbed enough sunlight to warp the case.

    I'm hoping someone here can give me some info on slicer settings. I'm using Cura 4.3, printing on white PLA this time (I may reprint again using PETG down the road).

    My main question is how to address Bryan's comment on thingiverse to "Be sure your slicer fills the posts between the USB jacks and the locklip with something (infill or solid) or they will be brittle." I'm not sure how to interpret this comment, but saw the issues in the thread others mentioned, and I'd like to avoid them.

    Any help?

    It just means to look at the slicer's output and make sure that the little teeny posts where the Pi's connectors come through the case are filled with plastic, and not just a single extrusion that is hollow. A picture would probably help


    Same thing for the "locklip" which are the two big snaps on the top of the case that join it together, although that's rarely an issue because they're relatively big.

    Thanks Bryan! For some reason, I was thinking that you meant I needed to fill the gap across the posts with support material. Totally missed the point!

    One other question: Didn't someone make a sliding back case for the 4.3? I found the files for the one for 4.2, but I could have sworn there was one for 4.3 as well. But it's been 2 years since I was looking, so I'm not sure. Just thinking about options...
