Spot Universal Mounting Plate

Working with Spot I found the need for a mounting system that makes it easier to mount sensors and instruments. The current t-slot system on Spot was a little limited for smaller instruments. Two things drove the need for this; some of the bigger instruments needed to be removed before I could swap the battery and I didn't want to make a big unique stand for each instrument. 

Specs (Measure the pockets to make sure nuts & bolts will fit)

• Nut & Bolt- 1/4” - 20
• Mounting point spacing 20 mm
• x27 Mounting points (# of nuts you'll need)
• Plate’s mounting point x6 160mm (aligned for Spot’s T-slots)
• Overall Dimensions 180mm x 100 x 10mm

These specs may not be suitable for all applications so I've also provided the Fusion 360 model to make it more accessible to modify.

Why didn't I use T-slot tracks?

For large bulky items, the small t-slot bolts loosened during long operations. Nuts and Bolts felt a more secure way to hold the instruments down. I might consider designing a T-slot variate down the road.

This could be useful for other purposes, but this is designed for Boston Dynamic's Spot. 

Update Feb 2025: Added a version with all possible mounting points, removing the pockets.

Printing Notes

Check the layer change the make sure that time is provided to place the nuts in the part. This may change depending on print settings.
