About a month ago, I started down the path to try to create:
(in my best sarcastic George Carlin voice) Scared Stiff Inspired, Slingshot Alternatives
You can follow along the first part of this adventure by clicking here.
front: single color extruded, masked then painted back: dual extrusion Red and Grey Kodak PETG.
First, I tried a transparent red PLA from 3D Universe and dissolvable PVA for supports.
This yielded a really decent single-material result, though the inclusion of PVA pushes up the build cost by a couple bucks.
-Not a huge deal, these are just for me… or friends that ask for them but it also takes a bunch of time to clean up the PVA boogers or let them dissolve all the way. It ties up a build plate for 12-24 hours while it dissolves.
But what I really wanted to do is to get a decent dual-extrusion print template, separating out the transparent red from the original from the opaque parts. The idea being, if I could match the red translucent and print the rest in grey, each one is just a little detail paint work away from being closer to the originals.
In order to do multi material / multi extruder prints, you need a model that dissected into pieces.
Though not perfect, I eventually ended up with decent enough cutouts for a multi material print.
Getting the model broke into components pushed the limits of the capabilities of Shapr3D and my skills in this arena. Shapr3D doesn’t give you a great way to perform contoured or free-hand cuts so I ended up duplicating the model into three copies and erasing away portions of the model with varied overlapping edit-cylinders used to mask out subtraction zones.
I tried an EDU copy of Solidworks as well but I have more learning in that area before I can be effective. A couple days ago, I ran across Mesh Mixer, which may end up being a better solution for my use case in the future.
Kodak makes filament? Yep and it is really quite decent too. Good price, the spools have smooth cylinder walls and roll well and the material properties are very consistent. They are even food safe.
I’m mostly okay with the luminosity of the translucent PETG. The color is a little off from the original but a stickler could print on clear and used translucent hobby paints to tint in the red.
I still need to paint the feet lime green but so far my play testing set is holding up.
Have a Scared Stiff and need slings? You can pull down my models from here:

(please note the current prototypes still have a few small flaws but they are definitely playable)
