I opted to use 3mm wooden dowel to pin them together. I have included a 1:1 floor plan to help position the supports but this is to be used as a guide only.<br><br>I have also listed the wheels as optional as I ended up using two salvaged hoverboard tyres and built the rims around these dimensions but any type of wheel can be attached.&nbsp;</p><p>I would also like to add that to ensure a tight fit some of the parts might require some light sanding but I feel this adds to the building experience.&nbsp;<br><br>&nbsp;</p><figure class="table"><table style="border:2px solid #000000;"><tbody><tr><td style="border:1.5px solid
