Fit my debur tool perfect, as well as a similar designed hand drill tool.

Great simple deaign!

Great design. Used double sided tape instead of fasteners.

Worked great at catching all the dust.

Excellent details and so fun to play with and modify lighting options. Printed tracks in TPU, did do by object on 1 plate and the firt turned out perfect but the second has some sticky spots. May dry filament again and try again or just print both in PLA as others have said they work just as well. Using the Kid Remote Controller for Blade and Lights only version, though could use a 2-axis control for the ripper up/down (left/right). Suggestion for OP & others: I did notice after installing the hubs the motors began to slip and stall more. After removing and test spinning them I realized it wasn’t the hubs, but in stead the chassis causing the issues. The “spokes” the hubs slode onto were expanding the innder hub into the outter. I shaved off about 2-3 layers of print from all four (areas circled in red and pieces on cutting mat) and the wheels spun like butter after. Could have been my prints only but would be something to try if your tracks are not spinning easily AFTER installed.

Perfect controller for kids and simple vehicles. I printed 1-acis controls for both sides. I did have a hard time getting the screws fully tightened, seemed like the holes either got narrower the further down or were not deep enough. I did print in PLA Silk so that could be why as well. Have not done it yet, but may drill a small hole or modify the cover for the board to allow for visibility of the light to make sure it is on/off and connected.

Some better instructions would be nice. Had to flip between the model and picutres to figure out where pieces went.

overall printed fine, but once assembled was too hard for 3 year old to turn. Recommend designing some handle or larger base to hold onto while turning handle. Felt the base twisting and bending while trying to rotate the handle.

Fit great with WoodenEdu brand train tracks on Amazon.

Great details, even inside the tunnel.

Never seen cleaner threads. Ends spun on very easy!

Great print overall! No problems with the print, but the recommended 16mm long socket screws are a bit long on the outside two holes and they stick out enough to dig into your palm.

printed by objects to reduce the purges. printed and went together great. Printed in PLA Silk+

simple but great tool

Had to file down the tab on the inside just a bit for flunger to move smoothly.
