Not much to say here. If you found this, you know what you need :)

Don't hesitate to hit the ❤ and show some love. I'm always happy to hear from you in the 🗩 comment section. If you have problems printing my files: tell me in the comment section too!

Provided files

I do like to have real CAD-files, when downloading things from others. Most users don't provide files other than .STL-files. These are useless for further manipulation or quick changes. So I'll provide the following files to you:

Updates

• 2026-01-15 The .step file of the lid was the same as the bottom part. Corrected.

• 2021-12-11 Files: V1. Changelog: 

  • Basepart:

    • connector-blades don't stick out of the part anymore

    • 2 holes added to solder wire to the connectors and guide them through the top

    • added polarity signs

    • 4mm holes for M3 Ruthex inserts
       

  • Lid:

    • 2 holes added to solder wire to the connectors and guide them through the top

    • added polarity signs

    • holes for M3 countersink screws (ISO 10642 / DIN 7991)
       

• 2021-12-10 first upload. Files: V0

Is it easy to build/assemble?

In V0 there are a few holes you could drill bigger to add heat inserts to one of the parts. Or just glue the two parts together.

If there's interest I'll add more versions with countersunk holes. It's easy to do yourself in FreeCAD, just edit the “Holes” feature and edit:

Theres a 1mm slot to add a strip of 0.2mm 7mm wide hilumin strip (the stuff you connect Li-Ion cells with). Just fold it 4 times and press/glue it into the slot.

Remember: FreeCAD and STP-Files provided, just modify to your hearts content!!!

Is this thing finished?

Kinda…

Print Settings

If you'd like to attach stuff to the “lid”-part later with screws, just print that part 100% filled. Makes drilling holes much easier!

Rafts: Not necessary

Supports: Not necessary

Resolution: 0.2 … 0.3. Works great at 0.3mm layer height

Perimeters: 3 and more

Infill: 25%-100%

Filament: PLA, PETG, ABS, ASA, …

Notes:

Post-Printing

No supports needes, thus no cleanup.

Assembly

I recommend using super glue (CA) to join the parts. It does work perfectly with PLA, PETG, ASA, ABS if you do it correctly.

The key here is to use activator spray!

1. clean both surfaces with alcohol and let evaporate

2. spray the “lid” part with activator and let evaporate

3. add a fair amount of CA glue to the base part

4. put two 3mm nails/dowel pins in two diagonal holes

5. slide the two parts together and clamp them together

The glue sets immediately, that's why using pins to align the parts is essential when working with CA activator.
