When you are adding upgrades to a 3D printer, the first fork in the road is often whether you need more visibility or more mechanical control. The LED Light Kit for Sparkx i7 3D Printer Print Viewing and Nozzle Checks is built around watching the print, while the 10Pcs Silver Metal Belt Retainer Plates for 3D Printer Extrusion Hardware Parts is about holding belts in place. They overlap only in their general category of maker hardware, and the difference in listed prices may help you decide which priority matters more.
Quick verdict
The LED Light Kit is the pick for Sparkx i7 owners who want a clear line of sight to the nozzle and print bed. The 10Pcs Silver Metal Belt Retainer Plates is the pick for makers who are reinforcing belts on a 3D printer or CNC gantry and want a 10-pack at a lower listed price.

Where each product wins
Where the LED Light Kit wins
It takes the visibility-focused side of this comparison. The description points to bright LED lighting, a USB-connected layout, and a model-specific design around the Sparkx i7, so it suits someone who wants to watch layer changes, first layer adhesion, and nozzle moves clearly.
Where the Belt Retainer Plates win
They take the mechanical side. With M3 hole compatibility and a rectangular washer structure, they act as lock plates and belt clamp plates for printer or CNC hardware. The pack of 10 also gives you more pieces to work with.
Product notes
LED Light Kit for Sparkx i7 3D Printer Print Viewing and Nozzle Checks
The LED Light Kit is the higher-priced item in this head-to-head at USD 19.43. Its main appeal is the focused light source: the description highlights bright LED lighting to help you watch layer changes, first layer adhesion, and nozzle movement. The kit uses a USB-connected layout with wiring leads and connector modules, so it comes across as a complete add-on rather than a bare bulb. For Sparkx i7 owners, the model-specific fit makes it a more intentional option than a generic light strip. That same specificity is also the limitation: if your printer is not a Sparkx i7, the design may not match your setup, and the listed price is the higher of the two.
10Pcs Silver Metal Belt Retainer Plates for 3D Printer Extrusion Hardware Parts
Priced at USD 15.63, the 10-pack of silver metal belt retainer plates is the lower-listed-price choice here. These are small metal lock plates, around 1.50cm long and 0.50cm wide, designed as rectangular washers with M3 hole compatibility for belt fixing and clamping. The description positions them as suitable for CNC machine parts or 3D printer accessories, supporting gantry hardware and bottom platform stability. With 10 pieces in the pack, you get spare units for multiple belt points. The limitation is that they serve a purely mechanical role: they will not help you see the print, and the listing focuses on generic hardware rather than a specific printer model, so you need to match them to your own belt setup.
Final choice by use case
For a Sparkx i7 owner who wants to watch nozzle checks and print progression, the LED Light Kit addresses a real usability gap. For a maker assembling or repairing a printer frame or CNC gantry, the 10Pcs Silver Metal Belt Retainer Plates offer a quantity pack at a lower listed price. If you can only pick one, let your immediate project decide: lighting for observation, or plates for mechanical retention.
