<b>Update 24/01/2021:</b> I just realized that the OpenSCAD design source code did not contain the correct value for the belt width. So I have uploaded a fixed version of that file. Note: ---- I have uploaded a remix of this design featuring a smaller belt (60x400mm): https://www.thingiverse.com/thing:4598219 I do like the smaller size of the sanding block much better for hand sanding. So if you are new to this design, I suggest to print the remixed one instead of this one. But if you prefer a larger sanding block, the design presented here is what you are looking for. Description ----- This is a sanding block that uses standard sanding belts 75mm x 457mm. Changing the sanding belt is very quick using the two excenter levers. The design is inspired by a video from I SIMPLY BUILT IT (search for "The Ultimate Hand Sanding Block" on youtube). Advantages: ---- - 3D printed :-) - change sand paper quick and easy - sand paper fits perfectly - perfectly flat and hard block for precise sanding e.g. of edges - sanding belts are cheap and readily available in this standard size - sanding block can have any color you like Disadvantages: ---- - Block might be too big for small hands - Might break when falling to the floor (not tested yet - also no testing planned for the near future) - not cheap to print (requires a lot of material) I have printed the parts using PETG. All parts must be printed with the flat side down. 2 excenter levers have to be printed lying on their side. Additional materials required: ---- - screws ISO7380: - 10pcs M4 x 12 - 1pc M4 x 20 - 5pcs M4 x 30 - 4 washers 6.4mm x 20mm - 2 bolts 6mm x 40mm (the same one as ikea uses on their ivar shelves) OpenSCAD source code included. <b> Happy printing! - And then please post a Make! Thank you very much! </b>
