Please confirm the applicable models based on the hardware configuration on this page.

AlohaMini2 structural parts can be printed with PLA, PETG, ABS, or similar FDM materials. The parts are designed for a Bambu P2S-class printer.

Recommended Settings

Setting	Recommendation
Wall loops	4-6
Infill	15-25%
Support	Enable where required by the slicer

For the best strength, use 6 wall loops on load-bearing parts.

Printed Parts

Print the STL files from:

AlohaMini2/hardware/mobile_base2/stl/

Unless listed otherwise, each STL file is printed once.

O_Main_Assembly_Post4.stl	1
O_POST4_Connector_Base.stl	1
O_T_Connector_Cross_Bar.stl	1	Printed substitute for the aluminum T-frame
O_T_Connector_Dowel_Pin_12_25.stl	1	Printed substitute for the lift-axis steel pin
OB_Buck_Converter_Mount.stl	1
OB_Chassis_Bearing_Cover.stl	3

Material Notes

Material	Notes
PLA	Easiest to print, but lower strength and heat resistance. Good for general test builds.
PETG	Tougher than PLA, but stringier and more prone to rack/gear tooth adhesion. Use PLA or dedicated support material for support interfaces when possible.
ABS	Stronger and more heat-resistant, but more likely to warp. Use an enclosed printer, such as X2D, and control chamber temperature.

Chassis Printing

The chassis segments are large and can warp during printing. For the chassis, use the print-optimized STL when available:

OB_Chassis_Segment_1of3_PrintOptimized.stl

Printed Substitutes

If the BOM-listed aluminum extrusion for the T-frame or the chassis steel pins are not available, printed substitutes can be used. However, printed substitutes will significantly reduce structural strength. Use metal parts for the final build whenever possible.
