Didn't realize, I'd be cut off in my post... Lost my other lines retyping from memory
So I decided to create my own since I own a 3d printer... Basically I took some bar stock metal from Lowes (Home improvement store) and built a set of stirrups for my wife. I've gone through 3 versions, and I may be doing a 4th... I'll post pictures (not issue sorry) if interested, as well as detailed instructions and STL files (or Fusion360 links if you want to edit) My wife approved and gave some positive feedback on them (changes for comfort.) They have some side to side wobble, but not much and are pretty nice. My wife said she'd be very milling to use again.
1) Drill press - hand drill may work but bar stock is a bit hard to drill by hand without breaking bits
2) Drill bits sizes: 3/8 inch, 5/32 inch, 3/16 inch
3) Hacksaw/Sawzall to cut the bar stock metal
4) Screw drivers
5) 3D printer - I have a Monoprice Ultimate (Wanhao d6 clone)\
6) Hot air gun/rework station - not neccessay, but will help make a nice shiny smooth finish
1) 3D printer filament, I used PETG, but PLA would work and first version was like this
2) 1/2 inch bar stock in square tube - Need 2 sections of about 3 feet each
3) 3/8 inch bar stock rod (non-threaded) - I purchased 2x 3 foot sections, but may be able to purchase 1 if height works.
4) 5/16 inch threaded rod
5) Nuts and washers fro the 5/16 threaded rod (x
6) Some M3 and M4 screws in 30mm length
