Speed Control Cabinet

thingiverse

Update: 20th Feb 2019 I've just added a new front panel (PWM Panel.stl) designed to hold a 12v-40v PWM controller instead of the servo tester. I've also included a "blank" version of this panel onto which you can glue whatever printed control box suits your fancy. A heavy equipment RC control box is intended to house a servo tester, an ESC, and a lipo, allowing you to control a brushed or brushless motor without it being tied into a radio. I'm currently using two of these boxes to power a shaker and a conveyor in the garden while I play with my R/C excavators. The servo tester I designed the box for is an HJ "RC188" that I bought from eBay for under ten pounds. Its 4-digit display fools my friends and neighbours into thinking there's more involved in separating and transporting sand and gravel around the garden than there is. The front panel which houses the servo tester has a small recess for an ESC switch, so you don't need to fiddle around inside the cabinet to get your equipment moving. I've included two variations of the cabinet body: one with a ventilated back for use in hotter places than England and the more normal one with a solid back for where some splash protection might be useful. There's also a potential wire exit right in the centre of the back of the panel that you can open out yourself with a 6 or 7mm drill if you decide to use it.
