Modular Conveyor

Frame Side Variants

The model has three different frame side types, depending on the function of the module.

TT Motor Drive Side 

This is the recommended default drive option

• Designed for the MakerSupply / Bambu Lab TT motor

• Simple 5 V DC motor drive via USB connector

The Bambu lab TT-motor slides directly into the printed frame. 

Speed can be controlled by the Bambu Lab IA002 Speed controller

The motor compartment is closed with a printed cover, secured using:

4 × M2 self-tapping screws

Servo Drive Side (alternative drive, not needed when using the TT-motor)

• Frame side with servo mounting opening

• Designed for continuous-rotation servos

• Suitable for speed and direction control via software

Passive / Universal Frame Side

• Used as the opposite side of a driven module

• Also used for non-driven modules

• Designed symmetrically so it can be mounted left or right

• Used for hand operated conveyors with the Hand Crank (no motor)

This makes the system orientation-independent and simplifies multi-module layouts

Drive Sprockets

The belt loops around the drive sprockets. 

• Carefully remove all support material from the drive sprocket.

• The sprocket has a hexagon opening for a shaft 

   

The TT-motor shaft with corresponding hole, is used to connect  the TT-motor to the sprocket

Hand crank

Servo mounting

• When using a servo motor, the servo horn can be mounted to the drive sprocket using a standard servo horn. The horn normally comes with your servo, as alternative you can find standard servo mounts on makerworld.

• If necessary, adjust the lenght of the servo horn to ensure proper fit with the sprocket

Passive (non-drive) sprockets

The hexagon shaft without hole can be used on sides where no motor / drive system is present.

Belt Assembly

• Belt modules are connected using pieces of filament as hinge pins.

  Just cut pieces from your filament roll and insert them in the holes to connect the hinges.

   

The conveyor length can be extended by adding extra frames using connectors

When extending the conveyor lenght with extra modules, no sprockets are required at the connecting modules. Sprockets are only required at the start and end of the conveyor. On the middle parts of the conveyor, long (thicker) shafts can be used. 

Belt guides are used to support the belt. There are 3 lengths of belt guides. 

Short Belt Guide

• Sprocket clearance on both ends

• Used for fully driven single modules

Medium Belt Guide

• Sprocket clearance on one end only

• Used when extending the conveyor with additional modules

Long Belt Guide

• No sprocket clearance on either end

• Used for middle modules in multi-segment conveyors

Frame Legs

• Frame legs are used to connect two sides

• Leg-heigth can be configured in the parameters of the parametric model maker

• Assemble one frame side with the belt guide and the sprockets

• Place the lower belt shafts

• Mount the belt over the sprockets and over the lower guide shafts

  • Lower guide shafts prevent belt sagging

• Attach the opposite frame side 

• Connect the two frames together using the frame legs.

Top Guides

Top guides form the upper edges of the frame alongside the belt.

Available in two variants:

• Full module length

• Half module length

Both are generated parametrically based on the selected module length.

Endcaps - Two endcaps are available

• closed endcap

• chute endcap

Poop Chute Module

An optional poop chute module is available for 3D printer integration.

• Top opening for filament waste

• Side cutout automatically scales with belt height + leg height

• Designed to align correctly with:

  • Bambu Lab P1S

  • P2S

  • X1C
