A quick and simple design, to keep my newborn busy with fresh toys. More designs to follow as time emerges. In later designs I'll add chamfers and fillets to soften the edges. About 80mm long when printed to scale. I have not put much thought into this. CAUTION! I suggest using PLA as it's non-toxic Use YOUR OWN disgression when considering the safety of your child. If in doubt - DO NOT USE! I am not liable for any and/or all consequences of the use of this item, in any shape, form, variation, or purpose.
