Remote Pendant Up Down Hoist by gustafson_cj

I saw Brian Brocken's YouTube video (https://www.youtube.com/watch?v=d8us3OWgS1A) of a 3D Printed High Torque Gearbox that he used like a Winch to Tow his car, and I wanted to use it to make a Hoist for my garage. Brian's Gearbox has an amazing Gear Ratio of 162:1, and I paid the $5 to download his STEP files - well worth the money. After printing it, I needed a remote control pendant to operate my new hoist.
This Remote Control project is a 3D Printed Pendant that includes a rocker switch to control "UP/Down" functions, and a Momentary Push Button switch to activate the Hoist (I Didn't want the hoist to be able to run indefinitely, hence the need for momentary switch). Two push button switches would also work, but I didn't have them on hand.
Printing:
This pendant includes 3 files that are assembled with 5mm screws x8mm long. The Face Plate was printed in Red PLA, with a filament change to White PLA for the top letters. The Letter Faces were finished with "Ironing" setting in PrusaSlicer. The Bottom Plate and Sides were printed in PETG. There are recesses for 5mm nuts.

Prusa i3 MK3S
0.2mm Layer
20% infill
Print the parts with supports "everywhere" and then insert the rocker switch into the face plate. Insert the Face Plate into the Side Wall ensuring it is flush at the surface. Then insert the bottom Plate containing 3 hex nuts. Side walls on the bottom plate press the face plate firmly in place. Insert 3 screws and tighten. Route cabling, solder, and insert the momentary switch to finish it off. The momentary switch "Snaps" into place completing the assembly.
I also made a small project box with 4 relays that take the signals from the remote pendant and send voltage to my DC motor and reverse polarity for UP/DOWN functionality.
