Parallettes for Home Gym

My daughter wanted some Parallettes to use in her home gym.  I designed these to accommodate a Pine Furniture Leg I bought from Bunnings (Australian hardware store) as the bar between the end supports.  I cut the embedded screw off the leg and cut the remainder of the leg into two equal pieces for use as the horizontal bars between the printed end supports.

The furniture leg, ostensibly 735mm long by 44mm diameter, was found to be more like ≈42.5mm in diameter - so I designed the mounting hole to be 43mm in diameter for a snug, but not overly tight, fit.  To ensure the bar stays in its mounting hole, I've included a hole in the top so that an 8G sized screw can be inserted to keep the bar in place.  The screws don't have to be done up overly tight.  They merely locate the bar in position and don't take any load themselves.  Just ensure that the 8G screws are longer than say 20mm (and less than 50mm) and have a non-countersunk head.

If you have a different sized piece of wood for the bars - I've included the STEP file so that the design can be altered to suit your circumstances.

I've also included the link to the Onshape document I used for design.  I've used variables for the majority of the design - so if you want to change anything - simply change the values in the variables and the design will automatically update.  The link is:

Printing Parameters:

• A pretty simple print.
• Material - PLA or PETG
• Layer Height - 0.2mm
• Perimeters - 5
• Infill - 15% Cubic
• No supports required.  The models should be in the correct orientation already with the large bar mounting hole facing upwards.

The included 3MF file is the project file with all the settings I used to print on my Prusa XL.  The STL is just a single instance of the shape with no print settings applied.
