eSUN 3D Printer Flexible TPE 83A Filament 1.75mm Dimensional Accuracy +/- 0.05mm 1KG (2.2 LBS) Spool 3D Printing Material (WHL #103)

Printer filament. Well, not directly, but in a way.

I guess this could also be a rant since it’s not about the filament itself, but more an issue of packaging. This concerns eSun, which I avoid because of this, but for this very filament, I needed to buy eSun.

eSun makes TPU (they call it TPE, same thing really) filament in 83A shore hardness. I don’t think anyone else does, and very few do similar materials, especially in the 1.75mm DIY filament diameter and not for industrial use in the 3mm realm. The smaller the number, the softer the material is. […]


MicroQR scanner phone apps (#R23)

I’m not reeeeally into app recommendations, but that one bothered me for a long time…so here it goes:

For all your barcode needs on a mobile phone: Use the Cognex scanner! Available here for Androids and there for low hanging fruit.

Why the recommendation? Because, for reasons unknown to me, no standard camera app on both systems, nor any other barcode app that I could find for Android does support MicroQR codes. Basically everybody does Code 128 and 39, some do weirder stuff like interleaved 2-of-5, and 2D apps often support things like standard QR, Datamatrix or Aztec. […]


For Dell Laptop DC Power Charge Converter Adapter Cable Cord 7.4*5.0 to 4.5*3.0 mm Female (WHL #102)

Here’s something not to burn your house down with: DC power supply adapters.

My lighbox currently draws power from the 3D printer power supply, which does work, but has its limitations. Sure, I do have to move down the gantry to take photos in the first place, so the printer will be on anyways, but I am not able to run it during prints (time lapse?) due to power constraints. The build plate heater is 400W and only gets pulsed on-off (so no linear “oh 200W will do at the moment” regulation), and the power supply is a 500W unit from MeanWell. […]
