The Ultimate Arduino Uno R3 Box for MPCNC - no screws

thingiverse

This is the one and only MPCNC Arduino Box... just kidding. It's one amongst all the others. This one is designed to be used without screws or glue - all clicky. The Arduino fits quite snug. I put it in without having the shield installed. After getting it in without breaking the clips the CNC-Shield can be placed on top. The fan (40 x 40 x 11 mm) also had to be kind of forced into position but stays there reliably. The fan blows right into the stepper-drivers and the air is being released through the openings at the bottom of the box. Make sure to have enough cable left to be able to put the lid with the fan next to the box when working in it. The hole for the 12 V CNC-Shields cable has a diameter of 6 mm. If a plug is preferred the original clamps of the shield has to be removed. The lid is secured by two clicky noses and the stepper cables are laid right below the lid to not having to cut cables or plugs when making changes to the hardware or wiring. I printed it on an Ender-3 with PLA+ Speed: 60 mm/min Layer: 0.16 mm Infill: 100% Nozzle: 0.4 mm Nozzle-Temp.: 200 °C Bed-Temp.: 60 °C No supports when turning it bottom down (had to turn it by 90° in Cura) The surface quality was a bit annoying, probably due to calibration issues and an opened window right next to the printer. I think the writing on the box is to small for 0.4 nozzle snd 90° rotation. The design itself is really ok in my view but due to the depth of the box getting the Arduino in requires some patience. I look forward to your suggestions for improvement or for your remakes of this one.
