Sportsman + 3D print: Lil Doggy

[HumboldtEF]

Nice work on the tranny, I really enjoy redesigning stuff like this myself. I can see you're pushing things to the limit and I like it

Thanks! I'm definitely enjoying it.

Awesome work

Finally got some time to work on the chassis, and I think is ready to be tested!



Printed all the parts, disassembled the old Lil'Doggy and installed the new one.



Lil' Doggy 2.0! Is a roller. Next will be to relocate electronics. Now that the motor is upfront, I'll need to check where to leave the battery. I also want to add weight on the rear axle, so I'll probably build some Tungsten holders for the AR44 axle similar to what I did in the front. Have some ideas to try... I like how this is coming together!

Done with electronics, it's alive again. Now I need to install the body and probably do some trimming since overall the rig is way lower, so the body might start interfering articulation. Finally, test on the rocks!

Here some pics before and after:

Finished installing electronics and mounting the body. Tested it out on the rocks and think is a solid performer. Ofcourse you need to get to comps to actually push the limits, but so far so darn good.

Here some quick video testing: https://youtu.be/0ZXbI2b-GjU

Not sure about the durability yet, need to test and do some more abuse, but seemed pretty strong so far! What I expect from people back is feedback so I can improve it in future.

I also built some tugsten holder for AR44 rear axle, to balance the weight (extreme front weight right now) and keep it super low.



Still want to make a version that goes inside the wheel, but will need to build a pocket kind of wheel with internal rings like the ones on the front for the rear. But, so far works nicely.

I'm uploading my STLs here if you guys want to try this out!

Thingiverse sucks, the website is full of errors and the designs keep disappearing without any reaons. I moved the design here:

Looks great! What orientation did you print the transmission case/skid?

Printed standing straight. Support only when touching bed, assuming your printer is able to print bridges (nowadays I think almost every printer does). With my Ender3v2 I printed it in Nylon this way, with fan default to 0 but allowing it to go up too 100 on overhangs (Cura does it automatically for you), and came out great in PETG and Nylon (which is supposed to be the hardest).

Very nice work.
Looks awesome

Wow! This is a huge and hecking awesome job! Please tell me how long did it take you for all this? You motivated me to do something like that too! What kind of 3D printer did you use? I just don't have it yet, and I've been thinking for a long time about whether I need it or not, but I saw this thread and it became the last sign for me to buy a printer. Very cool! And tell me, please, how much material was spent on everything that you did?
