3D printed Ergo parts: SLA vs. FDM?

3D printed Ergo parts: SLA vs. FDM? - Lemmy.world

Hi All, I’m planning to print a plate & case for a handwired 46-key split kb. I have access to both SLA & FDM printers at a fab lab, so wondering which printer tech would be best to print various parts such as keycaps, plate, case etc. Function’s more important than looks for me. I’m allowed to use PLA or TPU for the FDM, and the default resin (ABS-like?) for SLA. I’m thinking: - Keycaps: SLA (I want really thin keycaps) - Plate: ?? (not sure what’s better for a thin & durable plate that allows a bit of flex when typing) - Case: FDM (Due to costs, and easy to embed screws & magnets) What do you think?

Replaceable battery while travelling for wireless split keyboards?

Replaceable battery while travelling for wireless split keyboards? - Lemmy.world

Hi folks. I’m trying to find a good way to mount the batteries for a wireless split keyboard such that battery replacements can be done easily while travelling internationally. As someone who’s now stuck with a dying LiPo battery directly soldered to my nice!nano while travelling, I’m struggling to find battery replacement options that are NOT online orders. Most local shops don’t have the 3.7V thin-ish LiPos that I often see in wireless splits, and the language barrier certainly makes finding things more difficult. So, with this in mind, I’m thinking of making a dedicated battery slot for each half that could fit a rechargeable AA or AAA-sized LiPo, which can be easily bought from shops at the airport or shopping mall. However, I’m unsure if any additional circuit or component is required for those AA/AAA-sized LiPos to work with a split keyboard (in terms of voltage). Has anyone tried to use such batteries for your split keyboards, or have seen a project that uses them? Also, if not AA/AAA-sized LiPos, what battery types would you suggest for this scenario?
