3.5 inch Event Day Counter, 4-Digits

3.5 inch Event Day Counter / 9cm Tage-bis-zum-Ereignis-Zähler

When you need to display a certain amount of anything (remaining days until event; pieces in Stock; days until retirement etc.), you probably prefer a simple compact display stand with easy readable numbers. Here you are. Additionally you'll have thrill and fun puzzling to assemble the numbers.

The digits are printed in two colors, with different front- and back sides.

Note the trick with the g-bar of the display – when the bar is active, there must be a gap on the opposite side to preserve the aesthetics. (So one of the two smallest parts (this are the ones with the g-gap) always has to be in the middle (#HINT)).

Next hint: a piece marked with an „8“ on the back has only one intended use: to construct the number 8 (who would have thought that . . .).

When using different print material, check if you have the correct print size of the Digit parts:

Four pieces of any digit, correctly inserted in one slot, must give a space dimension of at least 0.12‘ (3mm) between the upper edge of the digit and the top edge of the stand to give the cover strip (the lid) a chance to fit properly.

If you notice that the measurement gives a result that doesn’t match the specification, try printing a set of Digits, reducing the Scale Factors of x and y to 98% or 97%(UNLOCK THE SCALE-LOCK BEFORE, for you don’t want to reduce height z simultaneously!!!)

So, what parts do you need for for a complete device?

„Stand_4-slots“ (color 1)

„Lid-cover-strip“ (color 1)

„4xLid-spare-compartment“ (color 1)

„Dot_3x3mm“ (color 2)

4x „Digits_1Set-low/mid/top-Layer“ (color 1 and 2):

If you are new to multi-material-print, you have to combine the 3 files (low/mid/top-Layer) to one multi-color-stl. How is it done?

- Open Prusaslicer

- Click on the „Add“-cube (or Ctrl+I)

- select ALL THREE „4x Digits_1Set-xxxx“-files (hold Shift and mark all three)

- Click „ok“

- Prusaslicer recognizes an object with multiple parts: click „Yes“

Now all 3 files will be merged – with one Problem: the part „Digits-1Set-topLayer-LIFT-Z-4_6mm“ is located underneath the upper left triangle of the digit parts. To lift it:

- click on its name in the right middle box of Prusaslicer; go to „object manipulation“-box; -

- change the „position-z-value“ to 4,6mm.

The colored angle will hop on top of the upper left triangle.

Now choose you desired colors for the Digit (according your MMU lanes), or you insert „color change“ if you will do it manually, slice the stuff and count the days until your retirement (or any other event you are greedy for).

I PRINTED WITH 0.4mm NOZZLE

1st LAYER 0.3mm

NEXT LAYERS 0.35mm

. . . (so the Digit triangles have 2 colored layers, then 13 one-color-layers, then again 2 colored ones).

If there are problems with accuracy of fit, tell me, I'll correct it.

Good luck!
