Lasercut Linear Guide Carriage

thingiverse

This is a customizable carriage for linear guide applications. The guide itself is any rectangular profile but I designed the carriage with masson screed profile in mind. Adjustment screws allow to tighten the wheels support against the profile. To have the carriage parallel to the profile, the screws are installed on one side while the opposite is left on its stops. Washers are used to keep the wheels in the middle of their axle. Video available on YouTube Instructions Adjust the variables for your purpose Set the view to flat_packed to get each individual pieces to cut Variables: All dimensions are in millimeters. View - View the carriage fully or partially assembled or view individual parts Show_Profile - Show the profile (the screed) in assembled views Part - Choose which individual parts to render In_2D - Enable 2D projection / laser cutting path Material_Thickness - Thickness of used the material. Material_Clearance - Thinnest part of the material, thinner may break easily. Carriage_Length - This value allows to extend the overall carriage length. Carriage_Wheel_Box_Length - This value allows to extend the length of the wheel support. Carriage_Wheel_Number - Number of wheels along rail axis. In most case, it's 2. Screed_Section_D1, Screed_Section_D2, Screed_Thickness - Profile dimension (Screed_Thickness is only used for display purpose). Bearing_Inner_Diameter, Bearing_Outer_Diameter, Bearing_Width, Axle_Diameter, Axle_Nut_Inscribed_Diameter, Axle_Nut_Thickness, Axle_Washer_Thickness, Axle_Washer_Outer_Diameter - Wheel hardware. Adjustment_Screw_Diameter, Adjustment_Screw_Nut_Inscribed_Diameter, Adjustment_Screw_Nut_Thickness - Adjustment screws hardware. Side_Screw_Diameter, Side_Screw_Nut_Inscribed_Diameter, Side_Screw_Nut_Thickness - Side mount hardware. Small_Clearance, Large_Clearance - Clearance used in many parts of the design.
