Simple Z-axis tensioner. Parts are held together by dovetail joints, two bolts need to be screwed to fix bearing carriage in place. Assemble the carriage with one 608 bearing first, not inserting the shaft all the way. Then slide it onto…
A beam compass, that is marginally better than some of the competing models. I personally like about it that it won't ever change it's value in the middle of the arc drawing, like usual compasses do. Firstly, it may be used with almost…
A holder piece for 2.5 kg PETG spools with outer d=260 mm, inner d=52 mm, and thickness of 110 mm. Held in place by 4 drywall srews. Parts fit together tightly, you may need to sand roller halves and apply lube to assemble.
Laser pointer mount for optics experiments. For mirror set, visit Mirrors for optics experiments
I'm a STEM tutor and am currently designing an affordable set of designs for an at-home physics experimental course. This is a first piece in series, the angle mount for optics experiments. Model consists of two parts: the main dial and…
It's a simple case with sliding lid. You need to print two sets of clips. Suitable for 5 standard wooden pencils and two pens/liners. Use fuzzy skin on outer shell of case for better surface finish and enforce brim for printing clips.
Bracket to hold two wood pieces together at relatively square angle. Nothing more to it. Print on the corner for maximum strength.
A set of mirrors to mount on top of the Vernier angle ruler . Mirrors with different curvatures should reflect laser pointer light in a different ways. You can use cloudy water in a glass, smoke or vape steam to visualize laser pointer…
A frame for a chalkboard, converted from standard photo frame. I've used 0.6 mm ferrous magnetic vinyl sheet glued to 2.3 mm 240*300 hardboard. The whole frame prints in 3 batches and requires 8 to 12 5*2 magnets, depending on your…
