Very beautiful model! I tried printing the tracks in TPU (first time printing TPU) with 0% infill. Still used the wheels since I had already printed them and, although they don't move too good, they still work. Very nice project!

very cool:) me and my 4 year old twins had so much fun printing/building this Thank you!

What a comprehensive and detailed model! Many thanks for the fun project! My learning experience: I happen to recently purchase ASA in a grey color, and had never printed with it before. This use of ASA may have effected some of the printing and fit issues I had - so I would recommend using PLA throughout. 1) Despite using the Textured PEI plate - some of the components I printed with ASA came loose during printing...this was resolved by adding an outside brim to components without significant surface area on the bed 2) The snowcat cab as oriented had corners lifting off plate/warping in ASA...and had to be oriented with the floor of the cab on the plate to increase plate surface area/adhesion, and provide more equivalent cross sectional printing areas (in hopes of reducing strain due to uneven cooling as the print progressed. 3) The front plow kept separating with ASA where the open slots traverse across the length of the blade... which was corrected by adding small "pinning" supports as shown in the photo Again, as one of the drawbacks of ASA is poor bed adhesion, and it has a higher melt temp (which I believe can lead to more thermal strain where dissimilar material volumes exist) - my guess is that these issues would not be encountered if PLA had been used - but I offer the issue and resolution up - in the event someone wants to print with ASA. Like Verman2019 below noted, I also tried to print the separately provided TPU track file (having just received TPU 95AHF in black), and similarly found the track to offer too much resistance to flatten into the required shape. (I estimate it would take 10+ pounds of force to be applied between the furthest outside wheels - which of course will just cause the PLA axles to bend and the track to try to return to it's original round shape. Instead I printed only the formed treads (as part of the full parts package) with the TPU, and they came out awesome - just understand that these will not be functional moving treads. The black doors seemed to be just a tad too big (maybe because of ASA cab) - and despite filing areas of interference, I ended up cracking one of the risers of the cab between the door and back window, as I tried to press in place. After re-printing at 98.55% in both directions (leaving thickness at 100%), they fit perfect, without stressing out the rest of the cab frame. I used some 0.035" Aluminum welding wire to fashion "cotter pins" to keep all the printed pins in place, and will add a couple of small machine screws to hold the small winch pullies in place (once I find them in my shop).

Awsome model. I tried tpu tracks and turned out way too stiff. I mixed and modeled fully working tracks from pla. Now to print the rest of the model.

Die Verbindungen bzw. die Löcher sind perfekt. Alles geht gut ineinander. Manchmal etwas streng aber es geht. Ein tolles Modell. Wenn alles fertig ist mach ich noch ein Foto und stell es rein.

Took me a few tries but once i worked past operator error print came out nice

I like your model very much! But I want to print this track part with soft materials. The existing walking structure is only for decoration, and the track will fall off when it moves. Can you upgrade the track and load-bearing wheel part? Thank you very much
