As I mentioned in the April post, the sound coming from the 3d printed Helix Composite Model I made was a bit noisy. I continued working on finding ways to eliminate the noise and eventually put together a small storage trunk with wood scraps from other projects (excluding the legs which were newly purchased) and made a cushion with the helix composite model. The model was still noisy, but the cotton batting and velvet fabric muffled the sound. Inadvertently, I experienced a benefit from sitting on the cushion. I will not say what it was until at least 20 people have printed and tested a cushion. The model is on Tinkercad.
To make a cushion, I placed printed parts on top of a pine board and stapled fabric over the printed parts, to the board. The pine board was recovered from an old project. The pine board and fabric are not necessary for testing the cushion. The printed parts can simply be taped together and placed on a floor.
Is Lightweight PLA needed for testing? Turns out, the answer is no. I started wondering about this and printed test pieces with PLA plus. As I write this post, my CR10 Mini is printing a large cushion part, intended for a bathroom bench with Printlife Pro PLA. It may be the subject of a future post. Feel free to comment about your test results.
