775 pro shield

[Masterofbuttons]

The 775 has worked wonders for our team's shooting mechanism, but we noticed the wire connections were quite vulnerable (prone to bending) and because they were placed on a moving part we worried about breaking them in competition. I couldn't seem to find anything to guard the motor connections, so to fix this I created a 3d printed shield to guard them and wanted to share it with anyone else who could make use of it!



The part uses a zip tie around the outside to hold it on the motor and keep anything from pulling on the wires, and comes complete with vent ports.



Here is the part file in in stl form

Hope it helps!

This is definitely something we're interested in! I'm concerned that the part looks like it closes off the 4 rear vent holes on the very back of the 775. Is this actually the case (no pun intended)?

[Masterofbuttons]

They're hard to see but there are holes in the part right over the vent ports so it doesn't block ventilation

This is awesome! I'm so grateful that you shared the file. We might use this if the EkoCycle can print them well. Are you soldering the wires onto the terminals or using a connector? I guess the connectors might not fit into the case.

Thanks!

Cool, we'll get some 3D printed then. Thanks for saving us a bit of design work this weekend

[Masterofbuttons]

Our team has been soldering short cables on, then attaching that with a connector other things, we printed ours out with an EkoCycle too!

This is an awesome idea. Thanks for the post and files!

Wow
You just took something off my list of things to do!!

Thanks a bunch for sharing!!

[IndySam]

Awesome, thanks.

Now if someone would just design an adjustable mount for a AndyMark Hall sensor I would be set

I just got a quote on Shapeways.com - about $15 per shield + $5 for shipping, delivery by March 3rd.

Not a bad investment if your 3D printer's being annoying.

I would recommend 3dhubs. Sometimes the hubs will even give you parts for free when they find out who you are.

Firstly, I'd like to thank you for sharing this fantastic design. Secondly, we need to make the grooves for the terminals a little wider in order to fit over our solder joints and it would be greatly appreciated if you could share the file as a Step or some other format that is more modification friendly than stl.

Thanks!

Out of curiosity, how are you actually connecting the wires to the motors? The connectors we use look like they would be too long for this to work.

EDIT:

Nevermind, I'm blind...

Could you post a picture of how you have these attached anyways? I'm still curious about how you've soldered the wires to the motors.

[Masterofbuttons]

I'll take a picture of how we've soldered them and post it here tonight.
