This is another Tiny Whoop (or Inductrix) case and battery holder. This one has a ring for batteries around the outside of the case. The case itself holds 28 batteries (fatbatt version holds 24). I never used the two recessed slots that some cases have in the bottom, so I didn't put any here. I also didn't put any holders in the lid, but there's definitely room if you wanted to. Having room for 28 batteries was more than enough for me.
- Standard case with 6mmx12mm battery holders: Whoop_Case_With_Batteries_Base_stackable.stl
- Fat battery version with 7mmx12mm battery holders: Whoop_Case_With_Batteries_Base_FatBatts.STL
- Fat battery version without stackable recess: Whoop_Case_With_Batteries_Base_FatBatts_non_stackable.STL
- Standard Top for either version: Whoop_Case_With_Batteries_Top_Plain.STL
- Top with 3mm thick lid for adding deep embossed text: Whoop_Case_With_Batteries_Top_3mm.stl
- Tall Top with 2mm thick lid: Whoop_Case_With_Batteries_Top_Tall_Plain.STL
- Tall Top with 3mm thick lid for deep embossed text: Whoop_Case_With_Batteries_Top_Tall_3mm.STL
I like to print the base out of something somewhat rigid (PLA, PETG, ABS, etc...) then print the top out of TPU or something flexible.
Update 2/4/17: Added Whoop_Case_With_Batteries_Base_stackable.STL. This version has a recess on the bottom that allows it to stack on top of the upside down lid when the lid is off.
Update 2/21/17: I added a new version of the case to accommodate larger batteries (250mah, etc...). This version is called "Whoop_Case_With_Batteries_Base_FatBatts.STL". The battery holders in this version are 7mm x 13mm, as opposed to the standard case which uses 6mm x 12mm. The outside of the case is the same size so the same top works. I also added two stl's to test your battery size before going ahead with the full print. If your batteries are still a little too large for the fatbatts version of the case you can experiment with scaling Fatbatt_7x13_Size_Checker.STL until you find the size you like, then use the same scale in your slicer for x and y of the base and top. Note that the fatbatts version will only hold 24 batteries as the 4 corner spots won't be large enough.
I also added a version of the lid that has a 3mm thick top to allow for deeper embossed text if you want to customize with your own logo/wording. Tinkercad works well for this. The thicker version of the lid is Whoop_Case_With_Batteries_Top_3mm.STL.
Update 8/22/17: I added a new fat battery version that doesn't have the recess in the base for stacking the lid (upon request). I also added two new versions of the lid that are 6mm taller. The original versions of the lid were not quite tall enough for some of the long batteries.
