Airsoft Chronograph Box [STL]

Chrono Box for AceTech AC5000 — built for easy indoor chrono & test firing

Designed to fit the AceTech AC5000 perfectly inside a standard ammo box with internal dimensions: 280×142×175 mm. Makes it simple to chrono and test your setup indoors without BBs flying everywhere.

Assembly
Uses 10×3 mm neodymium magnets to hold the top cover and sides in place — press-fit and solid. You can also screw the chrono holders in if you prefer; small 2 mm pilot holes are built in for alignment.
The feet also use 8× 10×3 mm magnets — tight fit, just press them in.

Add padding inside the box to protect it and absorb impact. 10 mm hard foam or a thin cushion works great.

Update Log
01/03/2024 – Added printable feet for horizontal chrono use (fits Prusa Mini build volume).

Printing notes

• 2–3 walls, 15–20 % infill
• Printed and tested on a Prusa MK3S+ with CCTREE PLA-ST in olive green
