SMD parts organiser fixed on the wall with double sided tape

For a long time, I wanted to make organiser for SMD parts that doesn’t take too much space in the workshop. Finding a particular item 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). Without any problem one tube should fit even a few hundred SMD elements in the 1206 package. Each organiser module is capable of holding 60 test-tubes. Modules can be easily combined together. Below I will try to describe how to make this organiser.

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 have it described. I prepared a simple spreadsheet in excel to print content stickers. Just customize it to your needs, print (in 2D 😉 ), glue two-sided tape, cut and glue over specially prepared lines for fixing 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 to 2.5mm.


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

Sticky pads:

Now we stick the pads to a strong 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 screws and washers into the front panel. Then put on the screws the 15mm washers from the back side of the panel. The next step is to apply the rear panel and apply the printed washers (the shorter ones) as well as the metal ones to the screws (after the rear panel is applied). The last step is to screw the sticky pads we previously threaded.


The project was made quite fast in Autodesk Inventor, below I have attached a few renderings:


Wall mounting & final effect:

After we finish the assembly, we can proceed to glue 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 🙂 ).
