SMD parts organiser fixed on the wall with double sided tape

For a long time, I wanted to make an organiser for SMD parts that doesn’t take too much space in the workshop. Finding a particular part in boxes with mixed smd tapes is a total nightmare, it is even worse when you need to find a particular capacitor (as you know they are not signed). It can be easily attached to the wall without drilling any holes. Because of the wall mount, the organiser is always easy to access and it does not take up valuable desk surface. I decided to use the popular 2 ml Eppendorf test-tubes with plastic hinges (they are very cheap, 200 pcs. for  about one dollar). One tube should fit even a few hundred SMD elements in the 1206 package without any problem . Each organiser module is capable of holding 60 test-tubes. Modules can be easily combined together. Below I will describe how to make this organiser step by step.

All parts

Needed components and tools :

  • Drill bit: 3 mm and 2.5 mm dia
  • M3 Tap
  • Very strong double sided tape
  • Standard double sided tape for stickers
  • Printed stickers sheets
  • 3D prints
  • M3 x 30 screws
  • M3 Washers (2 for each screw)
  • Eppendorf 2 ml test-tubes
  • Drill

3D printing:

Small items were printed in smaller batches to reduce the risk of lifting off one of them from the heatbed . Sticky pads should be printed from ABS, because they will be threaded later. Recommended print parameters: layer 0.25 mm, nozzle 0.4 mm.

Content stickers:

You can put in to the test tubes almost anything, but it is good to describe every container to know what is inside. I prepared a simple spreadsheet in excel to print some stickers that describe what is inside the test tubes. Just customize it to your needs, print in 2D 😉 , stick two-sided tape to the stickers, cut and apply them on the organiser front plate.

Reaming the holes:

The mounting holes on the front and back panel should be drilled with a 3 mm drill bit. The holes in the sticky pads should be prepared for threading. You need to drill these holes up to 2.5 mm to make sure that they are perfect.

Threading:

Then carefully tap the sticky pads (make sure the tap is straight).

Sticky pads:

Now we apply the pads to a strong double sided tape and cut the excess (it is best to stick the tape to the smooth side of the print).

Putting all together:

First, insert the bolts with metal washers into the front panel. Then apply the 15mm 3D printed washers from the back side of the panel. The next step is to apply the rear panel and the shorter 3D printed washers. The last step is to tighten sticky pads we previously threaded on the bolts .You need to apply more metal washers if bolt sticks out from sticky pad .

Design:

The project was made quite fast in Autodesk Inventor, below you can see a few renderings:

Wall mounting & final effect:

After we finish assembling, we can proceed to apply the organiser modules to the wall. Be careful to stick everything straight the first time, because peeling it off is practically no longer possible (without tearing the paint from the wall 🙂 ).
