POP Kiosk Collar (part)

This section contains CLIO documentation.

Overview

• 
• 
• 

The collar protects the exposed edges of the Raspberry Pi touchscreen display, decreasing the chances that the kiosk screen will be damaged from minor bumps and falls.  It is printed in two parts and held together by M2 screws.

Features

• Provides additional protection to the touchscreen display
• Rounded and tapered corners designed to reduce accidental snags
• Compatible with the POP kiosk cover for storage and transport
• Add color and contrast to your kiosk with swappable collars
• Can be used with a self-adhesive screen protector

Material

This part is printed with polylactic acid (PLA) or other sturdy plastic, such as Polycarbonate (PC) or Acrylonitrile styrene acrylate (ASA).

Printing This Part

Slicing

Orientation

Part	Notes	Example
Collar Front	We recommend printing the collar front with the flat edge attached to the build plate and the curved face pointed up. This will require the use of more supports, but will result in a better overall print result that requires less finishing.
Collar Back	We recommend printing the collar front with the thickest flat edge attached to the build plate and the curved edges facing up. This will require supports, but will result in a better overall print result that requires less finishing.

Settings

Collar Front

We start with the default "Standard Quality" 0.2 mm print profile. We recommend the following settings overrides:

Setting	Recommendation	Notes
Shell - Wall Line Count	3	This was increased from the default to increase the durability when higher amounts of stress are applied. This also completely fills in the sides and does not leave gaps between the walls.
Shell - Bottom Layers	4	This provides a good mixture of durability and material conservation.
Shell - Top Layers	4	This provides a solid top layer that is symmetrical with our bottom layer.
Infill - Density	20%	This part is intentionally partially hollow at the corners to add an air cushion if the kiosk is dropped.
Infill - Pattern	Tri-Hexagon Cubic Subdivision	These infill patterns provide good internal support in multiple directions.  Tri-Hexagon uses less filament but is also less durable.
Speed - Print Speed	40mm/s	For final production prints, we recommend printing slower than average to decrease stringing with small holes.
Support - Generate Support	Yes	This part has a lot of overhangs that require the use of supports.
Support - Support Structure	Tree	We highly recommend tree supports instead of normal supports. They take more time, but they require less filament and are much easier to remove from inside the case.
Support - Support Placement	Touching Buildplate	Only printing supports that touch the build plate are much easier to remove from this print.
Build Plate Adhesion - Adhesion Type	None	This part has a lot of contact with the print bed and should not require a raft.
Experimental - Small Hole Max Size	30mm	This will cause the printer to print slower when it is printing the screw holes.

Results

Printers

This part has been print tested with the following 3D printers:

Manufacturer	Model	Notes
Creality	CR-10 Mini	Excellent print quality. Reliable machine.
Creality	CR-10	Excellent print quality. Reliable machine.
Creality	Ender 3 S-1 Pro

Build Surface

This part has been print tested with the following build surfaces:

Method	Notes
Painter's tape
Glue stick	Creates an uneven and non-uniform first print layer appearance.
Adhesive build surface	First layer may have problems printing full height depending on type and hardness of build surface, but this does not affect the overall printability.
Polyetherimide (PEI) build plate	Some parts may require a raft if there are issues with the first layer adhering.

Filament

This part has been print tested with the following materials:

Filament	Manufacturer	Notes
Overture PLA	Overture	Excellent build quality and durability. Good for prototyping or production kiosks.
Amazon Basics PLA	Amazon	Decent build quality and durability. Recommended for rapid prototyping.
