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
• x58 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.

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

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.
