Montessori-Style Puzzle Toy for Infants/Toddlers

prusaprinters

<p>A Montessori-style puzzle toy to help toddlers develop and hone their hand-eye coordination skills.</p><p>No sharp corners.</p><p>I printed the parts with a 0.6mm nozzle and 0.3mm layer height but a 0.4mm nozzle will of course work fine too. I did not include knobs to avoid the need for supports. Instead, the inserts have screw holes designed for M4/#8 flat head machine or wood screws.  I used these knobs: <a href="https://www.amazon.com/gp/product/B077C92XXN/">https://www.amazon.com/gp/product/B077C92XXN/</a> but the screws included are unsuitable as they are not flat head and too long. Just get some M4-20 flat head machine screws at your local hardware store.</p><p>I used <a href="https://www.amazon.com/gp/product/B081R88DQC/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&amp;psc=1">iSANMATE Wood Filament 1.75mm, PLA+ Wood Filament 1.75mm, 3D Printer Filament 1 kg Spool (20% Wood Powder+80% PLA+)</a>. It's not a great wood filament, looks and feels way too plasticky but I think it's actually better for use by babies than filament with more wood. </p><p>For the inserts I used a variety of PLA filaments, including <a href="https://www.amazon.com/gp/product/B07J3TSND9">TTYT3D's amazing Shiny Silk filaments</a>.</p><p><strong>If you like what I'm doing…</strong><br/><strong> </strong><br/>…consider <a href="https://www.buymeacoffee.com/mix579">buying me a coffee</a>.<br/><img alt="orange_img.webp" src="https://media.prusaprinters.org/media/prints/66457/rich_content/928013a1-566f-400e-9729-5055e85c6131/image.png#%7B%22uuid%22%3A%2299831187-f75f-41b0-b091-abdef2db1098%22%2C%22w%22%3A170%2C%22h%22%3A37%7D"/><br/><br/><br/><br/><br/><br/><br/><br/><br/> </p>
