Integrated Twist Receiver, development stls
🕑 Added 2022-07-23 03:01:53 +0000 UTCThis is the first version of this idea I'm happy enough with to release, even though there are still a few changes to make. I'm putting this in a few private places because I'm not sure if there's issues I've missed and it's not done, but I love having a receiver that's got managed wires and less potential for pinch points. I also figure that the best way to get myself to finish up my ideas on this is to put it out and get some feedback.
This is very alpha, print at your own risk.
It's got a lube tube that drops all the way down for easy connection the back of the fleshlight while not fully blocking the air leaving the sleeve. It also supports up to 4 haptic coin cell motors, 10mm x 3mm. Heater options are up to you, but I like running two adafruit kapton heaters. Can easily use a carbon heater like the mod case too. There's a spot for a thermal sensor, DS18B20 is one I know some people use and comes with a long wire ready to crimp, usually. And of course, a servo at the top of the case provides up to 270 degrees of rotation. Wires are fully managed so there shouldn't be any snags.
This is assembled almost exclusively with M3x10 screws and M3x5x4 heat set inserts, aka "voron inserts". Metal tape (aluminum or copper) is used to close off the heater core, if you make this but aren't using a heater, regular tape would be fine, or just ask me and I'll send you a version with plastic there. Standard servos should all fit, regular horn style because it's what most people have.
4mm OD 2mm ID PTFE (like what a lot of printers use) is used for the structure of the wiring harness as well as lube delivery with a PTFE coupler, with the internal toy lube path using 4mm OD 2mm ID silicone tube. All wiring comes out the top of the case, I ended up budgeting about 90cm of wire to each run, 30awg for vibrators, 22awg for heating worked well for me.
Recommend low (5%-10%) infill with 3 perimeters (~1.2mm wall thickness) on all parts except for the "outer bottom" which would do better with medium (20%) infill and 4 perimiters (~1.6mm thickness)
I need to:
Reduce the interior case size so it's compatible with a stock receiver and add mod case adapter. (Original dimensions were from before I started to metal tape the heater on, which saves space.)
Add additional retention geometry, especially between the heater core and heater shell, and between the two halves of the outer receiver/case.
Reduce the wasted space in the back, both in length and possibly adding a taper.
Add gentle texture to outside
End of case connectors for easier connection and disconnection
