Description
Hello everyone!
Update 10.06.2026: Added insert for 96 rounds of 7.62x39 ammo (link)
Update 30.05.2026: uploaded inserts for revolver speedloader without place for speedloader (as per user request):
- 5 shot 44 Magnum (link)
- 6 shot 44 Magnum (link)
- 5 shot 38Special/357 Magnum (link)
- 6 shot 38Special/357 Magnum Model A (link)
- 6 shot 38Special/357 Magnum Model B (link)
Update: 25.05.2026: uploaded insert for .22WMR /.17HMR
Update 29.04.2026: uploaded corrected version of .45 ACP insert
Update 04.04.2026: Added inserts for:
- 8 shot .22LR Speedloader
- 7 shot .22WMR speedlaoder
- 5 shot .44 Magnum speedloader
Update 19.03.2026: Added dual stack insert for .22LR for TALL BOX for total 520 rounds of ammo, link to profile: here
 |  |
Update 18.03.2026: Added Insert for 6x357 speedloader - Model D (for N-Frame Revolver)
Update 12.02.2026: Reuploaded the .22LR insert because of issues with the box closing. The insert is now chamfered also on the sides so it won’t collide with the lid. Also, there is a small loading helper on the second plate as a bonus - it will allow you to pick 10 rounds each time :)
Update 09.03.2026: Added insert for .22LR (260 rounds)
Update 28.02.2026: Added insert for .45 ACP (77 rounds) :)
Update 27.02.2026: Added inserts for 9mm bullets in two versions:
- 150 rounds (Please note that this insert tends to catch on the lid when closing, as the first row of rounds is very close to the edge. You may need to slightly flex the lid in order to close the box. If this is an issue for you, please consider the 135-round version, which does not have this problem.)
- 135 rounds (one row less for better closing)
Update 07.02.2026: Added insert for .454 Casull (Model A) speedloader
Update 03.02.2026: Added inserts for:
- 6x22WMR Speedloader
- 8x22WMR Speedloader
- 5x45 Long Colt Speedloader
Update 27.01.2026:

For now, there is only an option for the standard-size box. I will add a module for the extended version later.
You can connect the modules horizontally and vertically. There are also six holes on the back for wall mounting.
To connect the modules, use the clips from plate 2. You can also add rails to connect modules vertically — just slide them in all the way.
Check the photos below for connection tips.

Update 05.01.2025: Added insert for 6 shot .22lr speedloaders
Update 04.01.2025: Added moonclip holder for standard and extended size box,
also added Inserts for .32 SW Long and .44 magnum speedloaders
Update 02.01.2025: Added insert for MODEL C speedloader (6x.357/.38) from here: link
Update 20.12.2025: Added inserts: 24x 12GA, 96x 6.5 Creedmoor
Added also alternative Lid for dual latch box with a place for nameplate:
Lid and empty nameplate is in this print profile: link
just add some text to empty nameplate in your slicer !
lid is compatible with both standard and extended height box (both dual latch)
Update 27.12.2025: A stacking frame has been added. The frame is compatible with both the tall and the low box.
The frame simply needs to be placed onto the bottom part of the box until it clicks into place (see print profile photos for details). Thanks to the frame, the boxes can be stacked on top of each other, minimizing the risk of slipping.

I'd like to present my modular boxes with interchangeable inserts.
Their main purpose is to store the speedloaders from my collection
you can check them out here: link.
But i have many more ideas for those boxes… :)
Standard height box have dimensions:
- external: 167mm x 125mm x 50mm (with hinges an latches)
internal: 160mm x 100mm x 45mm
Extended height box have dimensions:
- external: 167mm x 125mm x 78mm (with hinges an latches)
- internal: 160mm x 100mm x 73mm
For now there are two box variants available:
- Single-latch version (for standard height box) – easier to open and operate with one hand
- Double-latch version (for standard and extenderd height box) – provides more secure storage
To assemble the box, you only need a spring with a 5 mm diameter and a length between 10–15 mm.
For mounting the hinges and attaching the latch, you can use:
- M4x30 screws with nuts, or
- Plastic snap-fit pins, available as a separate print profile: link
The print profiles for the boxes have fuzzy skin enabled on the side recesses.
If you prefer, you can disable this feature in your slicer settings — doing so will reduce the print time by approximately 40 minutes.
