Giá Đỡ Tạ (Thiết Kế Khớp Nối, Không Cần Phụ Kiện)

A simple weight rack for small dumbbells. Slots together so it doesn't require any hardware. The weights are relatively light so it's more than capable of holding them. 

Update: Made some changes to the model to improve stability:

• Removed chamfers from slots, which caused fitments come loose easier
• Made the connectors taller so they anchor down better
• Removed chamfer from the bottom of the rack so it doesn't tip as easily
• Tolerances on my model I printed were 0.5mm but it was a bit loose so I lowered them to 0.3mm, should still be more than enough for any printer. 

----------------------------------------------------

Print flat since the overhangs can be a little harsh, might redesign those in the future. Also it allows the infill to show if that's what you want. Mine was printed with a 0.6 nozzle, but here's some settings with a 0.4 nozzle in mind:

• Material: PLA (I used Overture PLA Pro but normal PLA should work fine.)
• Layer Height: 0.2-0.28mm
• Perimeters: 4
• Top/Bottom: 0 (if you want infill to show)
• Infill: 15-20% Honeycomb (Any infill works, I just like the hexagons)

----------------------------------------------------

Below are the measurements your dumbbells will need to fit:

Top dumbbells:

• Handle Length: > 7.6cm
• Handle Diameter: < 3.4cm
• End Diameter/Width: < 7cm (measured at points for hexagonal dumbbells)

Bottom dumbbells:

• Handle Length: > 7.6cm
• Handle Diameter: < 3.8cm
• End Diameter/Width: < 4.25cm
