Description
Four section resistor storage solution for the full E24 series. The E24 series has 24 values each of which exist on 6 powers of 10. So for example: 1e0, 1e1, 1e2, 1e3, 1e4, 1e5, 1e6 or as it is on the labels: 1.0, 10, 100, 1k, 10k, 100k, 1M. That means there are a total of 6*24 = 144 different resistor values. Technically the E24 series is for 5% resistors, but it is easy and cheap to get all of these common values as 1% resistors.
These drawers could also be used for other small components and the labels could be easily made out of card stock instead of being printed. The full set of 4 frames, 24 drawers and 144 labels took a bit over 100 hours of printing time. The drawers are about 1.3 kg, the frames 0.67 kg, and the labels about 75 grams. (All in PLA at 15% infill.)
There is a hole in the back of the frame in the middle of each slot which is reinforced for mounting with standard wood screws. You can see the ones I used in the photos. The back of each drawers has a small indented section to fit over the screw head. Each section in the drawers has a rounded floor so that "scraping" components out is significantly easier.
I designed the whole set in Fusion 360. To make the labels easier to do I connected the various labels in a single group with very thin "bars" so that Fusion would allow them to be counted as a single body (which made patterning the text possible). These "bars" will be ignored by any slicer. If you want to make your own labels, use the following info:
Width: 25.8mm (or go a bit higher if you want a more snug fit)
Height: 18.2mm (and here I would suggest actually going a bit lower)
Thickness: 0.8mm (4 layers @ 0.2mm)
Corner fillets: 1mm (important to make the labels slide into the slots easily)
Number height: 8mm
Number font: Artifakt Element Black (nice because the 4 doesn't have a floating center)
Unit height: 9mm
Unit font: Arial (Bold)
You will then need to add in small bits to hold any floating inner areas (for 0,6,8 and 9)
2017-11-08 - Added an stl for test printing a compartment and an image showing the measurements.
2017-11-08 - Added a drawer version for use with 0.8 mm nozzles
2017-12-02 - Updated the 0.4mm and 0.8mm drawers with a better export that shouldn't cause issues in S3D. Fixed the 620 Ohm and 620 kOhm labels (they had been 640 by accident).
