Size the device pocket#

Choose Electronics tray in the design selector. Enter the whole device's width and length, including the parts that need to sit inside the pocket. Controls use millimeters.

Height below lip is the clear space above the floor. Allow for the device thickness and the vertical clearance you need. The live preview follows sliders and typed dimensions.

Choose the mounting layout#

  • Zip ties: adds two 1 mm-deep channels beneath the floor.
  • 1 bolt: adds an end tab with an adjustable offset from the tray center.
  • 2 bolts: places mounting tabs front-to-back or left-to-right.
  • 4 bolts: uses a rectangular pattern.

Every layout includes two pairs of side slots for device-retaining ties. For bolted layouts, set center spacing, hole diameter, and screw-head diameter. A saved compatible drone profile can supply the bolt pattern.

Rounded external tabs keep screw heads accessible. If the selected heads overlap the tray, the setting is rejected and the last valid model remains. Electronics trays reject asymmetric front/rear drone patterns rather than silently converting them to a rectangle.

Adjust fit and openings#

Expand Fit & openings to set side clearance, floor and wall thickness, tie width, cable-notch width, and an optional circular bottom opening.

Set cable-notch width to zero for closed ends. The bottom opening must preserve a support border. Tie slots are 1.6 mm tall; check your actual tie thickness and width.

Add retaining lips#

Lip over device adds two thin side rails above the pocket. The rails are 1 mm thick and initially overlap the device edges by 1 mm, separately from side clearance. The center remains open so flexible TPU sides can move during insertion.

Set overlap to zero for an open tray. Confirm that the chosen material, wall thickness, and print settings let the device pass the lips without damaging the part or electronics.

Save and print#

STL export produces one connected tray. A .mmproject retains the dimensions, mounting layout, lip overlap, device details, and drone reference. Older projects without lip settings keep their open-tray behavior until you increase the lip control.

Test device fit, cable routing, tie access, and retention with a sample print. Mount Maker does not determine those properties from the mesh alone.
