Description

A solution for mounting 9mm and 6mm 2mgt/2gt GT2/GT3 belts to mgn12 carriage with M2-SHCS or 2mm pin. Designed to handle high belt tensions. Versions for both inverted and normal belts.

Features

• Belt Pin
• Does not clamp the belt against the carriage, carriage-wipers or anything other than itself
• For monolith (inverted belts) it will not change the belt path (keeps the belt path perfectly straight)
• For normal belt direction there will be a ~0.8mm y offset
• Keeps within the confines of the carriage (unless using the external clamps)
• builds just 6mm out in y
• Tested with 15kg static load per belt

BOM

Part	Amount	Description
M2x25mm SHCS or 2x25mm PIN	4	Pin leaves more material, hence stronger.
		M2 SHCS for ease of use
		(only 2 screws if using single pin and clamp version (shuttle_clamper_body_v75)

Print Instructions

• Print it upright, the strength comes from the layer direction. printing it in the incorrect orientation will result in a weaker part.
• Use support (make sure your supports are tuned to the point where you're able to remove them carefully without breaking the part).
• 40%+ infill
• 4 perimitters
• 4 top and bottom layers
• 0.2mm layer height (or smaller)
• 0.4mm nozzle (or smaller)
• enable filling gaps

Part Instructions

shuttle_clamper_body_v101_inverted_belt_gt2_epdm

main body, for no loss in x. For inverted belts in EPDM (LL-GT2 E) and GT3. will be too loose for normal GT2 (rubber) belts. Should work with GT2 RF (rubber/normal) belts as well, but will slip sooner (<15kg)

shuttle_clamper_body_v96_*

main body, for no loss in x. For inverted belts gt2 rubber belts (LL-2GT RF). Too tight for GT2 EPDM or GT3.

shuttle_clamper_body_v75

Single pin, no teardrop lock. Meant to be used with m2_belt_clamp or m3_BeefyBeltClamp. GT2 rubber and epdm, and GT3.

m2_belt_clamp

small footprint belt clamp using m2 screws and heatset nuts.

m3_BeefyBeltClamp

Beefy clamp using m3 screws and hexnuts.

BOM - m2_belt_clamp

Part	Amount	Description
m2x4x3.5 Heatset Nut	6	4mm deep, m2 threads, 3.5mm outer diameter
m2x10mm SHCS Screw	6	m2x12 SHCS also works ok

BOM - m3_BeefyBeltClamp

Part	Amount	Description
m3 hexnut	6
m3x8mm SHCS Screw	6	m3x12 SHCS also works
