The original model is very cool, but I just wanted something a bit easier to print as I wanted to print lots of these to give to some junior school children visiting us and my printer at work has pretty poor bed adhesion. It also means there are now three nice flat surfaces that you can put text/logos on. I removed the hook at the back, slightly improved the feet/legs contact patch and redid the patch where the body meets the bed

Please note that if your printer over-extrudes at all the feet will jam and won't move as they should and if you force it (as I did before reducing the flow rate) the leg will snap as you can see in one of my make photos! :)

I did this entirely in Solidworks as I didn't have access to any of the mesh manipulation software I'd normally use at home so the part where I removed the hook isn't perfect, but you won't see it unless you're printing a massive version! :)

No supports/raft or brim should be needed to print. Print the first couple of layers slow though to ensure you get good adhesion at the beginning!

I've recently started printing it rotated 90 degrees in the slicer so the start/stop line is on the back instead of the right-side as in my photos. It looks better IMHO.

I've printed in eSUN PLA+ and eSilk.

The SS in some of the print photos stands for Senior School by the way!

Version 2: I found that the leg broke as shown in one of my make photo every time I removed it from the bed when not using PLA+, so I've made a second version of the robot where I rebuilt and added chamfers to that joint to make it stronger. I posted a third make comparing this new one to the original. The differences aren't huge - but the joint seems a lot stronger.

Version 3: I found that even that modified leg joint wasn't strong enough so there is also a 3rd version with even more extreme chamfers on the leg joint. You may not need this if you have a bed that releases well and/or you're using a strong filament. It's mainly because the bed on the Flashforge Adventurer 3 seems to grip like crazy or not at all and I'm using slightly fragile eSilk PLA!

Version 4: I increased the strength of the upper leg joint as if it's tough to break the leg loose from the main body, that's where it tends to break now I strengthened the other joint!
