Thank you CraftUnique and CraftBot for this challenge.  I loved Meccano and Lego when I was a kid, Clickaloo can be exactly that replacement for my kids. 

When I started downloading the parts and researching, I found some additional parts on www.clickaloo.com These parts have since been added by Thibaut FEIX @Sig to the Clickaloo full construction kit.  Unfortunately, my printer (a Snapmaker 3-in-1) only has a 125x125x125mm Build Volume.  This left me in looking into using some of the smaller parts and combining them to form a larger part...

Hole Large Arc Radial

For the Large Arcs, I can only print the 8 hole (8HLA).  This left me thinking how I can combine them to form a 16HLA.  However, further investigation revealed that there is a misalignment on the first and last holes of the arcs, compared to the other holes.  On all of the holes, one of the 8 pins are aligned on the radial, however, on the first and last holes, these pins are off by 11.25 degrees.  On the HMA (Hole Medium Arcs), the offset of these pins is 15.0 degrees and on the HSA (Hole Small Arcs), the offset is 22.5 degrees.  This puzzled me for a while and I contacted a number of people to determine why this would be? Was this a mistake or intentional?  I couldn't get answers and decided to design a new set of arcs where the first and last holes' pins are aligned to the radial.  I will submit these to this object for anyone to use.  These will be known as HLAR (Hole Large Arc Radial), HMAR (Hole Medium Arc Radial), HSAR (Hole Small Arc Radial).

Hole Large Arc eXtended

These new Radial Arc parts, however, doesn't resolve my limited print volume space.  In order to have a 16HLA (16 Hole Large Arc), I can use up to 8HLA parts and combine them to form 9HLA (two 5HLAs overlapping), or a 10HLA etc up to a 16HLA.  I realised that it will be fairly thick (10mm) on each of the overlapping joints.  This left me to redesign these connections to have them 2.5mm thick on the last hole, allowing a standard 5mm thick part at the overlap.  These new parts will be known as HLAX (Hole Large Arcs eXtended).  I decided the best would be to use different combinations of 5HLAX, 4HLAX, 3HLAX will be sufficient to form all of the different HLA parts.  To fill the remainder of the 2.5mm first and last holes, there will be a 1HLAX that is only 2.5mm thick to patch these ends.

Cylinders

One of my designs for the Clickaloo Design challenge required a cylindrical part with holes perpendicular to the radial.  I am aware that I could use 16HLA (16 Hole Large Arc) or 12MHA (12 Medium Hole Arc) with a number of 90SFA-I (90° Single Fold Angle – Inner).  However, having an off-the-shelve part would be handy for any Clickaloo fan.  I compared some of the Angle parts to determine the differences between the Inner and Outer parts.  The cylindrical parts were designed and named accordingly.  I then designed 16HLC (16 Hole Large Cylinders) Inner and Outer parts as well as 8HMC (8 Hole Medium Cylinders) Inner and Outer parts.  These are available for anyone to use.

Wheels and Axles

I particularly like the Wheels.  There is a need for a Small set, I thus designed a new SW (Small Wheels).  These will also be available for anyone to use.  A set of Wheels without an Axle is defeating the purpose of wheels.  I started designing some axles that can be used together with the wheels.  I'm still working on variable length axles, for now, there will only be a fixed number of lengths.  Please feel free to send me a Personal Message if you require a specific length.  I noticed the Clickaloo arduino mount submitted by Ian Taggart @IanTaggart and believe there needs to be an option to attach a gear to the axles to allow for robotic control.

Locking Pins

With large structures, there is additional pressure on the pins and they easily slip out of position, resulting in the structure collapsing.  I had the need to have a Lock on the pin and designed a Locking Pin as well as a Lock.  For the Click pins, the click has a 0.25mm separation below the Lock.  I made the locks 3mm thick to align more or less with the current pin extentions through the holes.
