IMPORTANT WARNING

Note that there are a lot of variables that affect parts fitment, e.g., flow rate, temperature, speed, etc. Please do a quick, test print for each filament type and color to test for fitting first before printing all the parts. This way you know that the filaments have already been calibrated and you're sure the fitting will be correct when you print the parts. I have provided the profile test print plate - BL PLA Basic for you to test.

If you find the fitting too tight, the easiest you can do to adjust the fitment is play with the the Flow ratio (see below). Keep reducing it by 0.01 until you find the right fit.

Using Bambu Lab PLA Basic Silver, I have not adjusted anything and the printed part fits exactly as intended. See video below. As stated above, depending on the filament to be used, you may have to calibrate first to get the right fitting.

INTRODUCTION

This is another expansion set for my Minecraft-inspired building blocks / base & diorama builder. This most recent expansion further shows the versatility of the design as base for a marble run featuring Steve and various mobs riding in mine carts! Pretty unique I should say as I'm yet to find an actual Minecraft-themed toy that combines building blocks and marble run in one that provides hours of interactive play!

FULLY CUSTOMIZABLE

The straight and corner tracks/ramps are the same size as the blocks and tiles of the Minecraft-inspired building blocks / base & diorama builder. You can re-use any blocks you already printed but I recommend printing the new pillar supports from print profile provided for better stability.

The tracks can be re-arranged and customized as long as it starts and ends in the elevator/lifter. See the assembly manual on how to create track arrangements on your own. After assembling the tracks, go ahead and customize the look by printing blocks from the Minecraft-inspired building blocks / base & diorama builder.

ADDITIONAL HARDWARE

This marble run uses 10mm steel balls for the mine carts and a TT motor to power the elevator/lifter to work. You can purchase these hardware from the Bambu Lab online store by clicking on the links below in the Bill of Materials section.

This minecart marble run is compatible with the BL Marble Run 003 kit. You can use the motor and plastic marbles that came with the kit on the tracks but the marbles will not fit the minecarts. Below is a video showing that the marbles from BL Marble Run 003 roll and fit this minecart marble run.

PRINTING AND ASSEMBLY

IMPORTANT NOTE: Elephant's foot (first layer too squished into the build plate) may cause the blocks to be tight. DO NOT REMOVE assembled blocks right away. Wait at least a day and due to material creep, the blocks will get loose over time.

Print all parts as oriented in the print profile. Glue will be needed to assemble some of the parts and are indicated in the Assembly Guide.
