gimbal for spot trace GPS tracker · 模型 238078
This is a gimbal for a Spot Trace GPS tracker. I made it at NK Labs for a high-altitude balloon launch. It is printed here in SLA Formlabs Grey Resin on a Form 2. There are two versions here. The second was made to reduce weight. It is untested. Some of the photos showing assembly were done in Formlabs Clear Resin. There are 3 concentric circular frames which can rotate about 2 axes. The hexagonal recess are for M3 nuts. The GPS mount is screwed to the center frame. The GPS is placed in the mount with logo side in. The GPS is kept in the proper orientation by gravity. There is a clamping plate to help you attach to your payload. There is an optional battery frame allowing for tight integration of the battery and gimbal. This allowed for better battery and gimbal positioning for better balance. Clamping plates are 40mmX50mmX6mm. The clamping plate holes are a loose 3.75mm diameter 15mm x 30mm apart with a 90 degree countersink. The mounting faces (clamps removed) are 156mm apart. The diameter of the outer ring is 152mm. The weight with GPS installed and screws is about 280 grams without the battery frame. Battery frame adds 29mm to the height with a 40mmx114mm footprint. Hole spacing is 98mm x 15mm. It can straddle a 71mm x 25mm battery. It adds about 60 grams of mass. Assemble and use at your own risk. For any launch, look up and follow your local regulations. And give NK Labs a shout out.
